Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592926, here are decompositions:

3 + 31592923 = 31592926
5 + 31592921 = 31592926
83 + 31592843 = 31592926
179 + 31592747 = 31592926
263 + 31592663 = 31592926
359 + 31592567 = 31592926
479 + 31592447 = 31592926
503 + 31592423 = 31592926

Showing the first eight; more decompositions exist.
