Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462226, here are decompositions:

157 + 31462069 = 31462226
223 + 31462003 = 31462226
277 + 31461949 = 31462226
283 + 31461943 = 31462226
307 + 31461919 = 31462226
409 + 31461817 = 31462226
463 + 31461763 = 31462226
673 + 31461553 = 31462226

Showing the first eight; more decompositions exist.
