Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514452, here are decompositions:

3 + 31514449 = 31514452
23 + 31514429 = 31514452
29 + 31514423 = 31514452
191 + 31514261 = 31514452
293 + 31514159 = 31514452
509 + 31513943 = 31514452
659 + 31513793 = 31514452
743 + 31513709 = 31514452

Showing the first eight; more decompositions exist.
