Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540434, here are decompositions:

17 + 31540417 = 31540434
71 + 31540363 = 31540434
137 + 31540297 = 31540434
173 + 31540261 = 31540434
193 + 31540241 = 31540434
223 + 31540211 = 31540434
227 + 31540207 = 31540434
271 + 31540163 = 31540434

Showing the first eight; more decompositions exist.
