Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536722, here are decompositions:

3 + 31536719 = 31536722
109 + 31536613 = 31536722
193 + 31536529 = 31536722
223 + 31536499 = 31536722
241 + 31536481 = 31536722
331 + 31536391 = 31536722
409 + 31536313 = 31536722
499 + 31536223 = 31536722

Showing the first eight; more decompositions exist.
