Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530282, here are decompositions:

13 + 31530269 = 31530282
71 + 31530211 = 31530282
79 + 31530203 = 31530282
101 + 31530181 = 31530282
109 + 31530173 = 31530282
139 + 31530143 = 31530282
239 + 31530043 = 31530282
281 + 31530001 = 31530282

Showing the first eight; more decompositions exist.
