Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540362, here are decompositions:

19 + 31540343 = 31540362
23 + 31540339 = 31540362
53 + 31540309 = 31540362
101 + 31540261 = 31540362
149 + 31540213 = 31540362
151 + 31540211 = 31540362
173 + 31540189 = 31540362
181 + 31540181 = 31540362

Showing the first eight; more decompositions exist.
