Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480574, here are decompositions:

  • 67 + 31480507 = 31480574
  • 193 + 31480381 = 31480574
  • 373 + 31480201 = 31480574
  • 457 + 31480117 = 31480574
  • 613 + 31479961 = 31480574
  • 757 + 31479817 = 31480574
  • 877 + 31479697 = 31480574
  • 997 + 31479577 = 31480574

Showing the first eight; more decompositions exist.
