Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624266, here are decompositions:

137 + 31624129 = 31624266
139 + 31624127 = 31624266
197 + 31624069 = 31624266
263 + 31624003 = 31624266
277 + 31623989 = 31624266
283 + 31623983 = 31624266
307 + 31623959 = 31624266
313 + 31623953 = 31624266

Showing the first eight; more decompositions exist.
