Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608844, here are decompositions:

23 + 31608821 = 31608844
107 + 31608737 = 31608844
131 + 31608713 = 31608844
257 + 31608587 = 31608844
317 + 31608527 = 31608844
347 + 31608497 = 31608844
503 + 31608341 = 31608844
677 + 31608167 = 31608844

Showing the first eight; more decompositions exist.
