Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462832, here are decompositions:

61 + 31462771 = 31462832
73 + 31462759 = 31462832
103 + 31462729 = 31462832
109 + 31462723 = 31462832
223 + 31462609 = 31462832
229 + 31462603 = 31462832
241 + 31462591 = 31462832
691 + 31462141 = 31462832

Showing the first eight; more decompositions exist.
