Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624546, here are decompositions:

89 + 31624457 = 31624546
179 + 31624367 = 31624546
197 + 31624349 = 31624546
263 + 31624283 = 31624546
269 + 31624277 = 31624546
419 + 31624127 = 31624546
557 + 31623989 = 31624546
563 + 31623983 = 31624546

Showing the first eight; more decompositions exist.
