Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725258, here are decompositions:

5 + 8725253 = 8725258
41 + 8725217 = 8725258
167 + 8725091 = 8725258
431 + 8724827 = 8725258
617 + 8724641 = 8725258
761 + 8724497 = 8725258
797 + 8724461 = 8725258
821 + 8724437 = 8725258

Showing the first eight; more decompositions exist.
