Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462666, here are decompositions:

17 + 31462649 = 31462666
83 + 31462583 = 31462666
89 + 31462577 = 31462666
113 + 31462553 = 31462666
227 + 31462439 = 31462666
233 + 31462433 = 31462666
293 + 31462373 = 31462666
317 + 31462349 = 31462666

Showing the first eight; more decompositions exist.
