Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514338, here are decompositions:

29 + 31514309 = 31514338
41 + 31514297 = 31514338
47 + 31514291 = 31514338
71 + 31514267 = 31514338
179 + 31514159 = 31514338
257 + 31514081 = 31514338
461 + 31513877 = 31514338
521 + 31513817 = 31514338

Showing the first eight; more decompositions exist.
