Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627194, here are decompositions:

43 + 31627151 = 31627194
61 + 31627133 = 31627194
73 + 31627121 = 31627194
103 + 31627091 = 31627194
167 + 31627027 = 31627194
227 + 31626967 = 31627194
251 + 31626943 = 31627194
311 + 31626883 = 31627194

Showing the first eight; more decompositions exist.
