Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514498, here are decompositions:

19 + 31514479 = 31514498
79 + 31514419 = 31514498
97 + 31514401 = 31514498
277 + 31514221 = 31514498
307 + 31514191 = 31514498
349 + 31514149 = 31514498
397 + 31514101 = 31514498
439 + 31514059 = 31514498

Showing the first eight; more decompositions exist.
