Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463228, here are decompositions:

31 + 31463197 = 31463228
61 + 31463167 = 31463228
67 + 31463161 = 31463228
151 + 31463077 = 31463228
331 + 31462897 = 31463228
397 + 31462831 = 31463228
421 + 31462807 = 31463228
457 + 31462771 = 31463228

Showing the first eight; more decompositions exist.
