Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627354, here are decompositions:

107 + 31627247 = 31627354
137 + 31627217 = 31627354
233 + 31627121 = 31627354
263 + 31627091 = 31627354
281 + 31627073 = 31627354
347 + 31627007 = 31627354
461 + 31626893 = 31627354
557 + 31626797 = 31627354

Showing the first eight; more decompositions exist.
