Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541396, here are decompositions:

37 + 31541359 = 31541396
127 + 31541269 = 31541396
163 + 31541233 = 31541396
223 + 31541173 = 31541396
283 + 31541113 = 31541396
349 + 31541047 = 31541396
379 + 31541017 = 31541396
457 + 31540939 = 31541396

Showing the first eight; more decompositions exist.
