Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514954, here are decompositions:

7 + 31514947 = 31514954
43 + 31514911 = 31514954
61 + 31514893 = 31514954
223 + 31514731 = 31514954
283 + 31514671 = 31514954
313 + 31514641 = 31514954
421 + 31514533 = 31514954
733 + 31514221 = 31514954

Showing the first eight; more decompositions exist.
