Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536926, here are decompositions:

79 + 31536847 = 31536926
97 + 31536829 = 31536926
103 + 31536823 = 31536926
193 + 31536733 = 31536926
229 + 31536697 = 31536926
313 + 31536613 = 31536926
397 + 31536529 = 31536926
523 + 31536403 = 31536926

Showing the first eight; more decompositions exist.
