Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598380, here are decompositions:

3 + 31598377 = 31598380
17 + 31598363 = 31598380
53 + 31598327 = 31598380
59 + 31598321 = 31598380
101 + 31598279 = 31598380
113 + 31598267 = 31598380
167 + 31598213 = 31598380
179 + 31598201 = 31598380

Showing the first eight; more decompositions exist.
