Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627330, here are decompositions:

11 + 31627319 = 31627330
41 + 31627289 = 31627330
83 + 31627247 = 31627330
113 + 31627217 = 31627330
179 + 31627151 = 31627330
197 + 31627133 = 31627330
239 + 31627091 = 31627330
257 + 31627073 = 31627330

Showing the first eight; more decompositions exist.
