Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540374, here are decompositions:

11 + 31540363 = 31540374
31 + 31540343 = 31540374
113 + 31540261 = 31540374
157 + 31540217 = 31540374
163 + 31540211 = 31540374
167 + 31540207 = 31540374
193 + 31540181 = 31540374
211 + 31540163 = 31540374

Showing the first eight; more decompositions exist.
