Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462262, here are decompositions:

193 + 31462069 = 31462262
241 + 31462021 = 31462262
283 + 31461979 = 31462262
313 + 31461949 = 31462262
421 + 31461841 = 31462262
439 + 31461823 = 31462262
499 + 31461763 = 31462262
691 + 31461571 = 31462262

Showing the first eight; more decompositions exist.
