Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462254, here are decompositions:

37 + 31462217 = 31462254
113 + 31462141 = 31462254
127 + 31462127 = 31462254
151 + 31462103 = 31462254
233 + 31462021 = 31462254
251 + 31462003 = 31462254
277 + 31461977 = 31462254
293 + 31461961 = 31462254

Showing the first eight; more decompositions exist.
