Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479236, here are decompositions:

109 + 31479127 = 31479236
163 + 31479073 = 31479236
277 + 31478959 = 31479236
499 + 31478737 = 31479236
643 + 31478593 = 31479236
757 + 31478479 = 31479236
1063 + 31478173 = 31479236
1213 + 31478023 = 31479236

Showing the first eight; more decompositions exist.
