Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467792, here are decompositions:

  • 23 + 2147467769 = 2147467792
  • 59 + 2147467733 = 2147467792
  • 233 + 2147467559 = 2147467792
  • 389 + 2147467403 = 2147467792
  • 461 + 2147467331 = 2147467792
  • 1091 + 2147466701 = 2147467792
  • 1109 + 2147466683 = 2147467792
  • 1151 + 2147466641 = 2147467792

Showing the first eight; more decompositions exist.
