Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522040, here are decompositions:

19 + 31522021 = 31522040
61 + 31521979 = 31522040
157 + 31521883 = 31522040
211 + 31521829 = 31522040
367 + 31521673 = 31522040
373 + 31521667 = 31522040
397 + 31521643 = 31522040
499 + 31521541 = 31522040

Showing the first eight; more decompositions exist.
