Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461094, here are decompositions:

47 + 31461047 = 31461094
83 + 31461011 = 31461094
167 + 31460927 = 31461094
257 + 31460837 = 31461094
263 + 31460831 = 31461094
311 + 31460783 = 31461094
557 + 31460537 = 31461094
653 + 31460441 = 31461094

Showing the first eight; more decompositions exist.
