Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627498, here are decompositions:

107 + 31627391 = 31627498
179 + 31627319 = 31627498
251 + 31627247 = 31627498
281 + 31627217 = 31627498
347 + 31627151 = 31627498
491 + 31627007 = 31627498
521 + 31626977 = 31627498
599 + 31626899 = 31627498

Showing the first eight; more decompositions exist.
