Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536758, here are decompositions:

61 + 31536697 = 31536758
151 + 31536607 = 31536758
229 + 31536529 = 31536758
277 + 31536481 = 31536758
367 + 31536391 = 31536758
397 + 31536361 = 31536758
571 + 31536187 = 31536758
661 + 31536097 = 31536758

Showing the first eight; more decompositions exist.
