Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598546, here are decompositions:

3 + 31598543 = 31598546
97 + 31598449 = 31598546
127 + 31598419 = 31598546
193 + 31598353 = 31598546
307 + 31598239 = 31598546
367 + 31598179 = 31598546
409 + 31598137 = 31598546
613 + 31597933 = 31598546

Showing the first eight; more decompositions exist.
