Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756490, here are decompositions:

19 + 8756471 = 8756490
31 + 8756459 = 8756490
53 + 8756437 = 8756490
89 + 8756401 = 8756490
97 + 8756393 = 8756490
109 + 8756381 = 8756490
157 + 8756333 = 8756490
167 + 8756323 = 8756490

Showing the first eight; more decompositions exist.
