Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536212, here are decompositions:

151 + 31536061 = 31536212
163 + 31536049 = 31536212
193 + 31536019 = 31536212
229 + 31535983 = 31536212
271 + 31535941 = 31536212
541 + 31535671 = 31536212
619 + 31535593 = 31536212
661 + 31535551 = 31536212

Showing the first eight; more decompositions exist.
