Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147550770, here are decompositions:

  • 31 + 2147550739 = 2147550770
  • 61 + 2147550709 = 2147550770
  • 73 + 2147550697 = 2147550770
  • 97 + 2147550673 = 2147550770
  • 103 + 2147550667 = 2147550770
  • 181 + 2147550589 = 2147550770
  • 199 + 2147550571 = 2147550770
  • 349 + 2147550421 = 2147550770

Showing the first eight; more decompositions exist.
