Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717738, here are decompositions:

61 + 8717677 = 8717738
181 + 8717557 = 8717738
229 + 8717509 = 8717738
349 + 8717389 = 8717738
397 + 8717341 = 8717738
409 + 8717329 = 8717738
499 + 8717239 = 8717738
607 + 8717131 = 8717738

Showing the first eight; more decompositions exist.
