Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625938, here are decompositions:

37 + 8625901 = 8625938
127 + 8625811 = 8625938
151 + 8625787 = 8625938
229 + 8625709 = 8625938
379 + 8625559 = 8625938
397 + 8625541 = 8625938
421 + 8625517 = 8625938
487 + 8625451 = 8625938

Showing the first eight; more decompositions exist.
