Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462672, here are decompositions:

23 + 31462649 = 31462672
83 + 31462589 = 31462672
89 + 31462583 = 31462672
191 + 31462481 = 31462672
233 + 31462439 = 31462672
239 + 31462433 = 31462672
359 + 31462313 = 31462672
383 + 31462289 = 31462672

Showing the first eight; more decompositions exist.
