Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541274, here are decompositions:

5 + 31541269 = 31541274
7 + 31541267 = 31541274
31 + 31541243 = 31541274
41 + 31541233 = 31541274
101 + 31541173 = 31541274
113 + 31541161 = 31541274
157 + 31541117 = 31541274
173 + 31541101 = 31541274

Showing the first eight; more decompositions exist.
