Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474468, here are decompositions:

71 + 31474397 = 31474468
149 + 31474319 = 31474468
167 + 31474301 = 31474468
251 + 31474217 = 31474468
461 + 31474007 = 31474468
491 + 31473977 = 31474468
659 + 31473809 = 31474468
761 + 31473707 = 31474468

Showing the first eight; more decompositions exist.
