Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157774, here are decompositions:

  • 3 + 157771 = 157774
  • 5 + 157769 = 157774
  • 41 + 157733 = 157774
  • 53 + 157721 = 157774
  • 107 + 157667 = 157774
  • 137 + 157637 = 157774
  • 251 + 157523 = 157774
  • 317 + 157457 = 157774

Showing the first eight; more decompositions exist.
