Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627600, here are decompositions:

23 + 31627577 = 31627600
41 + 31627559 = 31627600
89 + 31627511 = 31627600
227 + 31627373 = 31627600
281 + 31627319 = 31627600
311 + 31627289 = 31627600
353 + 31627247 = 31627600
383 + 31627217 = 31627600

Showing the first eight; more decompositions exist.
