Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498594, here are decompositions:

3 + 31498591 = 31498594
47 + 31498547 = 31498594
53 + 31498541 = 31498594
131 + 31498463 = 31498594
167 + 31498427 = 31498594
173 + 31498421 = 31498594
227 + 31498367 = 31498594
251 + 31498343 = 31498594

Showing the first eight; more decompositions exist.
