Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575622, here are decompositions:

11 + 31575611 = 31575622
59 + 31575563 = 31575622
101 + 31575521 = 31575622
173 + 31575449 = 31575622
269 + 31575353 = 31575622
311 + 31575311 = 31575622
389 + 31575233 = 31575622
401 + 31575221 = 31575622

Showing the first eight; more decompositions exist.
