Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577626, here are decompositions:

233 + 31577393 = 31577626
239 + 31577387 = 31577626
257 + 31577369 = 31577626
263 + 31577363 = 31577626
467 + 31577159 = 31577626
569 + 31577057 = 31577626
617 + 31577009 = 31577626
659 + 31576967 = 31577626

Showing the first eight; more decompositions exist.
