Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514846, here are decompositions:

7 + 31514839 = 31514846
157 + 31514689 = 31514846
193 + 31514653 = 31514846
313 + 31514533 = 31514846
367 + 31514479 = 31514846
373 + 31514473 = 31514846
397 + 31514449 = 31514846
607 + 31514239 = 31514846

Showing the first eight; more decompositions exist.
