Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462260, here are decompositions:

43 + 31462217 = 31462260
127 + 31462133 = 31462260
157 + 31462103 = 31462260
191 + 31462069 = 31462260
239 + 31462021 = 31462260
257 + 31462003 = 31462260
281 + 31461979 = 31462260
283 + 31461977 = 31462260

Showing the first eight; more decompositions exist.
