Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495622, here are decompositions:

19 + 31495603 = 31495622
31 + 31495591 = 31495622
199 + 31495423 = 31495622
271 + 31495351 = 31495622
349 + 31495273 = 31495622
409 + 31495213 = 31495622
619 + 31495003 = 31495622
643 + 31494979 = 31495622

Showing the first eight; more decompositions exist.
