Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536546, here are decompositions:

7 + 31536539 = 31536546
17 + 31536529 = 31536546
47 + 31536499 = 31536546
149 + 31536397 = 31536546
163 + 31536383 = 31536546
193 + 31536353 = 31536546
199 + 31536347 = 31536546
233 + 31536313 = 31536546

Showing the first eight; more decompositions exist.
