Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490094, here are decompositions:

5 + 31490089 = 31490094
17 + 31490077 = 31490094
37 + 31490057 = 31490094
71 + 31490023 = 31490094
131 + 31489963 = 31490094
151 + 31489943 = 31490094
193 + 31489901 = 31490094
211 + 31489883 = 31490094

Showing the first eight; more decompositions exist.
