Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461282, here are decompositions:

29 + 31461253 = 31461282
53 + 31461229 = 31461282
59 + 31461223 = 31461282
89 + 31461193 = 31461282
101 + 31461181 = 31461282
103 + 31461179 = 31461282
109 + 31461173 = 31461282
233 + 31461049 = 31461282

Showing the first eight; more decompositions exist.
