Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725342, here are decompositions:

23 + 8725319 = 8725342
89 + 8725253 = 8725342
239 + 8725103 = 8725342
251 + 8725091 = 8725342
359 + 8724983 = 8725342
701 + 8724641 = 8725342
863 + 8724479 = 8725342
881 + 8724461 = 8725342

Showing the first eight; more decompositions exist.
