Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498546, here are decompositions:

5 + 31498541 = 31498546
17 + 31498529 = 31498546
29 + 31498517 = 31498546
47 + 31498499 = 31498546
83 + 31498463 = 31498546
179 + 31498367 = 31498546
197 + 31498349 = 31498546
239 + 31498307 = 31498546

Showing the first eight; more decompositions exist.
