Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522868, here are decompositions:

151 + 31522717 = 31522868
199 + 31522669 = 31522868
211 + 31522657 = 31522868
271 + 31522597 = 31522868
277 + 31522591 = 31522868
409 + 31522459 = 31522868
457 + 31522411 = 31522868
541 + 31522327 = 31522868

Showing the first eight; more decompositions exist.
