Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627358, here are decompositions:

97 + 31627261 = 31627358
109 + 31627249 = 31627358
157 + 31627201 = 31627358
307 + 31627051 = 31627358
331 + 31627027 = 31627358
379 + 31626979 = 31627358
571 + 31626787 = 31627358
691 + 31626667 = 31627358

Showing the first eight; more decompositions exist.
