Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498716, here are decompositions:

13 + 31498703 = 31498716
59 + 31498657 = 31498716
157 + 31498559 = 31498716
167 + 31498549 = 31498716
199 + 31498517 = 31498716
349 + 31498367 = 31498716
367 + 31498349 = 31498716
373 + 31498343 = 31498716

Showing the first eight; more decompositions exist.
