Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540308, here are decompositions:

11 + 31540297 = 31540308
47 + 31540261 = 31540308
67 + 31540241 = 31540308
97 + 31540211 = 31540308
101 + 31540207 = 31540308
127 + 31540181 = 31540308
199 + 31540109 = 31540308
277 + 31540031 = 31540308

Showing the first eight; more decompositions exist.
