Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536282, here are decompositions:

59 + 31536223 = 31536282
79 + 31536203 = 31536282
181 + 31536101 = 31536282
229 + 31536053 = 31536282
233 + 31536049 = 31536282
263 + 31536019 = 31536282
373 + 31535909 = 31536282
461 + 31535821 = 31536282

Showing the first eight; more decompositions exist.
