Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536350, here are decompositions:

3 + 31536347 = 31536350
37 + 31536313 = 31536350
127 + 31536223 = 31536350
163 + 31536187 = 31536350
331 + 31536019 = 31536350
367 + 31535983 = 31536350
409 + 31535941 = 31536350
523 + 31535827 = 31536350

Showing the first eight; more decompositions exist.
