Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474190, here are decompositions:

  • 19 + 31474171 = 31474190
  • 61 + 31474129 = 31474190
  • 79 + 31474111 = 31474190
  • 157 + 31474033 = 31474190
  • 199 + 31473991 = 31474190
  • 283 + 31473907 = 31474190
  • 379 + 31473811 = 31474190
  • 409 + 31473781 = 31474190

Showing the first eight; more decompositions exist.
