Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749722, here are decompositions:

53 + 8749669 = 8749722
71 + 8749651 = 8749722
109 + 8749613 = 8749722
151 + 8749571 = 8749722
173 + 8749549 = 8749722
271 + 8749451 = 8749722
283 + 8749439 = 8749722
379 + 8749343 = 8749722

Showing the first eight; more decompositions exist.
