Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624414, here are decompositions:

47 + 31624367 = 31624414
71 + 31624343 = 31624414
83 + 31624331 = 31624414
131 + 31624283 = 31624414
137 + 31624277 = 31624414
197 + 31624217 = 31624414
401 + 31624013 = 31624414
431 + 31623983 = 31624414

Showing the first eight; more decompositions exist.
