Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462936, here are decompositions:

3 + 31462933 = 31462936
5 + 31462931 = 31462936
47 + 31462889 = 31462936
59 + 31462877 = 31462936
179 + 31462757 = 31462936
347 + 31462589 = 31462936
353 + 31462583 = 31462936
359 + 31462577 = 31462936

Showing the first eight; more decompositions exist.
