Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627474, here are decompositions:

83 + 31627391 = 31627474
101 + 31627373 = 31627474
227 + 31627247 = 31627474
257 + 31627217 = 31627474
353 + 31627121 = 31627474
383 + 31627091 = 31627474
401 + 31627073 = 31627474
467 + 31627007 = 31627474

Showing the first eight; more decompositions exist.
