Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463972, here are decompositions:

13 + 31463959 = 31463972
31 + 31463941 = 31463972
61 + 31463911 = 31463972
79 + 31463893 = 31463972
193 + 31463779 = 31463972
229 + 31463743 = 31463972
283 + 31463689 = 31463972
439 + 31463533 = 31463972

Showing the first eight; more decompositions exist.
