Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498576, here are decompositions:

17 + 31498559 = 31498576
29 + 31498547 = 31498576
47 + 31498529 = 31498576
59 + 31498517 = 31498576
107 + 31498469 = 31498576
113 + 31498463 = 31498576
149 + 31498427 = 31498576
227 + 31498349 = 31498576

Showing the first eight; more decompositions exist.
