Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536986, here are decompositions:

3 + 31536983 = 31536986
43 + 31536943 = 31536986
139 + 31536847 = 31536986
157 + 31536829 = 31536986
163 + 31536823 = 31536986
193 + 31536793 = 31536986
373 + 31536613 = 31536986
379 + 31536607 = 31536986

Showing the first eight; more decompositions exist.
