Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473178, here are decompositions:

  • 61 + 2147473117 = 2147473178
  • 421 + 2147472757 = 2147473178
  • 577 + 2147472601 = 2147473178
  • 709 + 2147472469 = 2147473178
  • 757 + 2147472421 = 2147473178
  • 919 + 2147472259 = 2147473178
  • 1069 + 2147472109 = 2147473178
  • 1087 + 2147472091 = 2147473178

Showing the first eight; more decompositions exist.
