Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627264, here are decompositions:

3 + 31627261 = 31627264
17 + 31627247 = 31627264
47 + 31627217 = 31627264
113 + 31627151 = 31627264
131 + 31627133 = 31627264
173 + 31627091 = 31627264
191 + 31627073 = 31627264
257 + 31627007 = 31627264

Showing the first eight; more decompositions exist.
