Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749630, here are decompositions:

3 + 8749627 = 8749630
17 + 8749613 = 8749630
23 + 8749607 = 8749630
41 + 8749589 = 8749630
59 + 8749571 = 8749630
173 + 8749457 = 8749630
179 + 8749451 = 8749630
191 + 8749439 = 8749630

Showing the first eight; more decompositions exist.
