Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514458, here are decompositions:

29 + 31514429 = 31514458
149 + 31514309 = 31514458
167 + 31514291 = 31514458
191 + 31514267 = 31514458
197 + 31514261 = 31514458
491 + 31513967 = 31514458
641 + 31513817 = 31514458
719 + 31513739 = 31514458

Showing the first eight; more decompositions exist.
