Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574626, here are decompositions:

137 + 31574489 = 31574626
173 + 31574453 = 31574626
197 + 31574429 = 31574626
257 + 31574369 = 31574626
263 + 31574363 = 31574626
659 + 31573967 = 31574626
773 + 31573853 = 31574626
929 + 31573697 = 31574626

Showing the first eight; more decompositions exist.
