Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540592, here are decompositions:

19 + 31540573 = 31540592
103 + 31540489 = 31540592
151 + 31540441 = 31540592
229 + 31540363 = 31540592
283 + 31540309 = 31540592
331 + 31540261 = 31540592
379 + 31540213 = 31540592
661 + 31539931 = 31540592

Showing the first eight; more decompositions exist.
