Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498858, here are decompositions:

5 + 31498853 = 31498858
11 + 31498847 = 31498858
29 + 31498829 = 31498858
47 + 31498811 = 31498858
311 + 31498547 = 31498858
317 + 31498541 = 31498858
359 + 31498499 = 31498858
389 + 31498469 = 31498858

Showing the first eight; more decompositions exist.
