Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598330, here are decompositions:

3 + 31598327 = 31598330
31 + 31598299 = 31598330
103 + 31598227 = 31598330
139 + 31598191 = 31598330
151 + 31598179 = 31598330
193 + 31598137 = 31598330
229 + 31598101 = 31598330
397 + 31597933 = 31598330

Showing the first eight; more decompositions exist.
