Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625940, here are decompositions:

107 + 8625833 = 8625940
131 + 8625809 = 8625940
233 + 8625707 = 8625940
251 + 8625689 = 8625940
353 + 8625587 = 8625940
419 + 8625521 = 8625940
431 + 8625509 = 8625940
461 + 8625479 = 8625940

Showing the first eight; more decompositions exist.
