Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577326, here are decompositions:

3 + 31577323 = 31577326
167 + 31577159 = 31577326
197 + 31577129 = 31577326
269 + 31577057 = 31577326
317 + 31577009 = 31577326
359 + 31576967 = 31577326
587 + 31576739 = 31577326
617 + 31576709 = 31577326

Showing the first eight; more decompositions exist.
