Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476236, here are decompositions:

67 + 31476169 = 31476236
79 + 31476157 = 31476236
139 + 31476097 = 31476236
163 + 31476073 = 31476236
223 + 31476013 = 31476236
283 + 31475953 = 31476236
307 + 31475929 = 31476236
409 + 31475827 = 31476236

Showing the first eight; more decompositions exist.
