Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462522, here are decompositions:

  • 41 + 31462481 = 31462522
  • 71 + 31462451 = 31462522
  • 83 + 31462439 = 31462522
  • 89 + 31462433 = 31462522
  • 149 + 31462373 = 31462522
  • 173 + 31462349 = 31462522
  • 233 + 31462289 = 31462522
  • 389 + 31462133 = 31462522

Showing the first eight; more decompositions exist.
