Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493792, here are decompositions:

  • 3 + 31493789 = 31493792
  • 13 + 31493779 = 31493792
  • 103 + 31493689 = 31493792
  • 139 + 31493653 = 31493792
  • 151 + 31493641 = 31493792
  • 181 + 31493611 = 31493792
  • 193 + 31493599 = 31493792
  • 199 + 31493593 = 31493792

Showing the first eight; more decompositions exist.
