Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494924, here are decompositions:

5 + 31494919 = 31494924
17 + 31494907 = 31494924
37 + 31494887 = 31494924
107 + 31494817 = 31494924
157 + 31494767 = 31494924
211 + 31494713 = 31494924
233 + 31494691 = 31494924
281 + 31494643 = 31494924

Showing the first eight; more decompositions exist.
