Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538722, here are decompositions:

3 + 31538719 = 31538722
11 + 31538711 = 31538722
29 + 31538693 = 31538722
233 + 31538489 = 31538722
311 + 31538411 = 31538722
389 + 31538333 = 31538722
461 + 31538261 = 31538722
569 + 31538153 = 31538722

Showing the first eight; more decompositions exist.
