Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651738, here are decompositions:

157 + 8651581 = 8651738
349 + 8651389 = 8651738
379 + 8651359 = 8651738
409 + 8651329 = 8651738
457 + 8651281 = 8651738
499 + 8651239 = 8651738
547 + 8651191 = 8651738
577 + 8651161 = 8651738

Showing the first eight; more decompositions exist.
