Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742148, here are decompositions:

  • 71 + 8742077 = 8742148
  • 89 + 8742059 = 8742148
  • 137 + 8742011 = 8742148
  • 197 + 8741951 = 8742148
  • 281 + 8741867 = 8742148
  • 347 + 8741801 = 8742148
  • 449 + 8741699 = 8742148
  • 461 + 8741687 = 8742148

Showing the first eight; more decompositions exist.
