Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749906, here are decompositions:

3 + 8749903 = 8749906
59 + 8749847 = 8749906
89 + 8749817 = 8749906
173 + 8749733 = 8749906
293 + 8749613 = 8749906
317 + 8749589 = 8749906
449 + 8749457 = 8749906
467 + 8749439 = 8749906

Showing the first eight; more decompositions exist.
