Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536026, here are decompositions:

7 + 31536019 = 31536026
43 + 31535983 = 31536026
79 + 31535947 = 31536026
199 + 31535827 = 31536026
229 + 31535797 = 31536026
433 + 31535593 = 31536026
523 + 31535503 = 31536026
607 + 31535419 = 31536026

Showing the first eight; more decompositions exist.
