Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463192, here are decompositions:

31 + 31463161 = 31463192
109 + 31463083 = 31463192
223 + 31462969 = 31463192
283 + 31462909 = 31463192
421 + 31462771 = 31463192
433 + 31462759 = 31463192
463 + 31462729 = 31463192
601 + 31462591 = 31463192

Showing the first eight; more decompositions exist.
