Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463132, here are decompositions:

109 + 31463023 = 31463132
163 + 31462969 = 31463132
199 + 31462933 = 31463132
223 + 31462909 = 31463132
373 + 31462759 = 31463132
409 + 31462723 = 31463132
523 + 31462609 = 31463132
541 + 31462591 = 31463132

Showing the first eight; more decompositions exist.
