Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498864, here are decompositions:

11 + 31498853 = 31498864
17 + 31498847 = 31498864
53 + 31498811 = 31498864
101 + 31498763 = 31498864
317 + 31498547 = 31498864
347 + 31498517 = 31498864
401 + 31498463 = 31498864
443 + 31498421 = 31498864

Showing the first eight; more decompositions exist.
