Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742812, here are decompositions:

73 + 8742739 = 8742812
139 + 8742673 = 8742812
241 + 8742571 = 8742812
271 + 8742541 = 8742812
283 + 8742529 = 8742812
313 + 8742499 = 8742812
349 + 8742463 = 8742812
433 + 8742379 = 8742812

Showing the first eight; more decompositions exist.
