Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624226, here are decompositions:

79 + 31624147 = 31624226
97 + 31624129 = 31624226
157 + 31624069 = 31624226
223 + 31624003 = 31624226
409 + 31623817 = 31624226
523 + 31623703 = 31624226
619 + 31623607 = 31624226
727 + 31623499 = 31624226

Showing the first eight; more decompositions exist.
