Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462032, here are decompositions:

11 + 31462021 = 31462032
29 + 31462003 = 31462032
53 + 31461979 = 31462032
71 + 31461961 = 31462032
83 + 31461949 = 31462032
89 + 31461943 = 31462032
109 + 31461923 = 31462032
113 + 31461919 = 31462032

Showing the first eight; more decompositions exist.
