Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518614, here are decompositions:

7 + 31518607 = 31518614
13 + 31518601 = 31518614
73 + 31518541 = 31518614
157 + 31518457 = 31518614
163 + 31518451 = 31518614
271 + 31518343 = 31518614
313 + 31518301 = 31518614
433 + 31518181 = 31518614

Showing the first eight; more decompositions exist.
