Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462366, here are decompositions:

3 + 31462363 = 31462366
17 + 31462349 = 31462366
53 + 31462313 = 31462366
149 + 31462217 = 31462366
233 + 31462133 = 31462366
239 + 31462127 = 31462366
263 + 31462103 = 31462366
359 + 31462007 = 31462366

Showing the first eight; more decompositions exist.
