Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739812, here are decompositions:

43 + 8739769 = 8739812
73 + 8739739 = 8739812
139 + 8739673 = 8739812
229 + 8739583 = 8739812
283 + 8739529 = 8739812
313 + 8739499 = 8739812
331 + 8739481 = 8739812
349 + 8739463 = 8739812

Showing the first eight; more decompositions exist.
