Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514430, here are decompositions:

7 + 31514423 = 31514430
11 + 31514419 = 31514430
29 + 31514401 = 31514430
139 + 31514291 = 31514430
163 + 31514267 = 31514430
191 + 31514239 = 31514430
239 + 31514191 = 31514430
271 + 31514159 = 31514430

Showing the first eight; more decompositions exist.
