Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627260, here are decompositions:

11 + 31627249 = 31627260
13 + 31627247 = 31627260
17 + 31627243 = 31627260
23 + 31627237 = 31627260
43 + 31627217 = 31627260
59 + 31627201 = 31627260
109 + 31627151 = 31627260
127 + 31627133 = 31627260

Showing the first eight; more decompositions exist.
