Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574078, here are decompositions:

  • 7 + 31574071 = 31574078
  • 31 + 31574047 = 31574078
  • 37 + 31574041 = 31574078
  • 79 + 31573999 = 31574078
  • 331 + 31573747 = 31574078
  • 439 + 31573639 = 31574078
  • 457 + 31573621 = 31574078
  • 577 + 31573501 = 31574078

Showing the first eight; more decompositions exist.
