Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592746, here are decompositions:

83 + 31592663 = 31592746
179 + 31592567 = 31592746
257 + 31592489 = 31592746
293 + 31592453 = 31592746
389 + 31592357 = 31592746
587 + 31592159 = 31592746
617 + 31592129 = 31592746
953 + 31591793 = 31592746

Showing the first eight; more decompositions exist.
