Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742912, here are decompositions:

173 + 8742739 = 8742912
223 + 8742689 = 8742912
239 + 8742673 = 8742912
383 + 8742529 = 8742912
401 + 8742511 = 8742912
419 + 8742493 = 8742912
443 + 8742469 = 8742912
449 + 8742463 = 8742912

Showing the first eight; more decompositions exist.
