Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510194, here are decompositions:

7 + 31510187 = 31510194
61 + 31510133 = 31510194
73 + 31510121 = 31510194
83 + 31510111 = 31510194
101 + 31510093 = 31510194
103 + 31510091 = 31510194
173 + 31510021 = 31510194
193 + 31510001 = 31510194

Showing the first eight; more decompositions exist.
