Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498588, here are decompositions:

29 + 31498559 = 31498588
41 + 31498547 = 31498588
47 + 31498541 = 31498588
59 + 31498529 = 31498588
71 + 31498517 = 31498588
89 + 31498499 = 31498588
167 + 31498421 = 31498588
239 + 31498349 = 31498588

Showing the first eight; more decompositions exist.
