Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536248, here are decompositions:

61 + 31536187 = 31536248
151 + 31536097 = 31536248
199 + 31536049 = 31536248
229 + 31536019 = 31536248
307 + 31535941 = 31536248
421 + 31535827 = 31536248
439 + 31535809 = 31536248
577 + 31535671 = 31536248

Showing the first eight; more decompositions exist.
