Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536962, here are decompositions:

3 + 31536959 = 31536962
19 + 31536943 = 31536962
139 + 31536823 = 31536962
229 + 31536733 = 31536962
349 + 31536613 = 31536962
433 + 31536529 = 31536962
463 + 31536499 = 31536962
571 + 31536391 = 31536962

Showing the first eight; more decompositions exist.
