Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627558, here are decompositions:

47 + 31627511 = 31627558
167 + 31627391 = 31627558
239 + 31627319 = 31627558
269 + 31627289 = 31627558
311 + 31627247 = 31627558
467 + 31627091 = 31627558
659 + 31626899 = 31627558
701 + 31626857 = 31627558

Showing the first eight; more decompositions exist.
