Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536370, here are decompositions:

11 + 31536359 = 31536370
17 + 31536353 = 31536370
23 + 31536347 = 31536370
83 + 31536287 = 31536370
167 + 31536203 = 31536370
269 + 31536101 = 31536370
317 + 31536053 = 31536370
353 + 31536017 = 31536370

Showing the first eight; more decompositions exist.
