Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536444, here are decompositions:

41 + 31536403 = 31536444
47 + 31536397 = 31536444
53 + 31536391 = 31536444
61 + 31536383 = 31536444
83 + 31536361 = 31536444
97 + 31536347 = 31536444
131 + 31536313 = 31536444
151 + 31536293 = 31536444

Showing the first eight; more decompositions exist.
