Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742908, here are decompositions:

61 + 8742847 = 8742908
271 + 8742637 = 8742908
331 + 8742577 = 8742908
337 + 8742571 = 8742908
367 + 8742541 = 8742908
379 + 8742529 = 8742908
397 + 8742511 = 8742908
409 + 8742499 = 8742908

Showing the first eight; more decompositions exist.
