Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536300, here are decompositions:

7 + 31536293 = 31536300
13 + 31536287 = 31536300
73 + 31536227 = 31536300
97 + 31536203 = 31536300
113 + 31536187 = 31536300
139 + 31536161 = 31536300
199 + 31536101 = 31536300
239 + 31536061 = 31536300

Showing the first eight; more decompositions exist.
