Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536542, here are decompositions:

3 + 31536539 = 31536542
13 + 31536529 = 31536542
43 + 31536499 = 31536542
61 + 31536481 = 31536542
139 + 31536403 = 31536542
151 + 31536391 = 31536542
181 + 31536361 = 31536542
229 + 31536313 = 31536542

Showing the first eight; more decompositions exist.
