Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536206, here are decompositions:

3 + 31536203 = 31536206
19 + 31536187 = 31536206
109 + 31536097 = 31536206
157 + 31536049 = 31536206
223 + 31535983 = 31536206
379 + 31535827 = 31536206
397 + 31535809 = 31536206
409 + 31535797 = 31536206

Showing the first eight; more decompositions exist.
