Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463020, here are decompositions:

41 + 31462979 = 31463020
89 + 31462931 = 31463020
131 + 31462889 = 31463020
227 + 31462793 = 31463020
263 + 31462757 = 31463020
269 + 31462751 = 31463020
431 + 31462589 = 31463020
443 + 31462577 = 31463020

Showing the first eight; more decompositions exist.
