Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463318, here are decompositions:

37 + 31463281 = 31463318
151 + 31463167 = 31463318
157 + 31463161 = 31463318
181 + 31463137 = 31463318
241 + 31463077 = 31463318
349 + 31462969 = 31463318
409 + 31462909 = 31463318
421 + 31462897 = 31463318

Showing the first eight; more decompositions exist.
