Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462636, here are decompositions:

47 + 31462589 = 31462636
53 + 31462583 = 31462636
59 + 31462577 = 31462636
83 + 31462553 = 31462636
89 + 31462547 = 31462636
197 + 31462439 = 31462636
263 + 31462373 = 31462636
347 + 31462289 = 31462636

Showing the first eight; more decompositions exist.
