Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592510, here are decompositions:

43 + 31592467 = 31592510
73 + 31592437 = 31592510
163 + 31592347 = 31592510
199 + 31592311 = 31592510
307 + 31592203 = 31592510
337 + 31592173 = 31592510
349 + 31592161 = 31592510
457 + 31592053 = 31592510

Showing the first eight; more decompositions exist.
