Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749822, here are decompositions:

5 + 8749817 = 8749822
71 + 8749751 = 8749822
89 + 8749733 = 8749822
233 + 8749589 = 8749822
251 + 8749571 = 8749822
353 + 8749469 = 8749822
383 + 8749439 = 8749822
401 + 8749421 = 8749822

Showing the first eight; more decompositions exist.
