Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446282, here are decompositions:

29 + 31446253 = 31446282
31 + 31446251 = 31446282
41 + 31446241 = 31446282
53 + 31446229 = 31446282
59 + 31446223 = 31446282
71 + 31446211 = 31446282
149 + 31446133 = 31446282
151 + 31446131 = 31446282

Showing the first eight; more decompositions exist.
