Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627510, here are decompositions:

137 + 31627373 = 31627510
191 + 31627319 = 31627510
263 + 31627247 = 31627510
293 + 31627217 = 31627510
359 + 31627151 = 31627510
389 + 31627121 = 31627510
419 + 31627091 = 31627510
503 + 31627007 = 31627510

Showing the first eight; more decompositions exist.
