Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702672, here are decompositions:

79 + 8702593 = 8702672
103 + 8702569 = 8702672
241 + 8702431 = 8702672
313 + 8702359 = 8702672
331 + 8702341 = 8702672
421 + 8702251 = 8702672
499 + 8702173 = 8702672
523 + 8702149 = 8702672

Showing the first eight; more decompositions exist.
