Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498566, here are decompositions:

7 + 31498559 = 31498566
17 + 31498549 = 31498566
19 + 31498547 = 31498566
37 + 31498529 = 31498566
53 + 31498513 = 31498566
67 + 31498499 = 31498566
97 + 31498469 = 31498566
103 + 31498463 = 31498566

Showing the first eight; more decompositions exist.
