Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624274, here are decompositions:

127 + 31624147 = 31624274
271 + 31624003 = 31624274
307 + 31623967 = 31624274
373 + 31623901 = 31624274
457 + 31623817 = 31624274
571 + 31623703 = 31624274
607 + 31623667 = 31624274
751 + 31623523 = 31624274

Showing the first eight; more decompositions exist.
