Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539422, here are decompositions:

73 + 31539349 = 31539422
139 + 31539283 = 31539422
151 + 31539271 = 31539422
181 + 31539241 = 31539422
193 + 31539229 = 31539422
349 + 31539073 = 31539422
379 + 31539043 = 31539422
643 + 31538779 = 31539422

Showing the first eight; more decompositions exist.
