Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514558, here are decompositions:

7 + 31514551 = 31514558
79 + 31514479 = 31514558
109 + 31514449 = 31514558
139 + 31514419 = 31514558
157 + 31514401 = 31514558
337 + 31514221 = 31514558
367 + 31514191 = 31514558
409 + 31514149 = 31514558

Showing the first eight; more decompositions exist.
