Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498564, here are decompositions:

5 + 31498559 = 31498564
17 + 31498547 = 31498564
23 + 31498541 = 31498564
47 + 31498517 = 31498564
101 + 31498463 = 31498564
137 + 31498427 = 31498564
197 + 31498367 = 31498564
257 + 31498307 = 31498564

Showing the first eight; more decompositions exist.
