Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598282, here are decompositions:

3 + 31598279 = 31598282
43 + 31598239 = 31598282
103 + 31598179 = 31598282
139 + 31598143 = 31598282
181 + 31598101 = 31598282
271 + 31598011 = 31598282
349 + 31597933 = 31598282
409 + 31597873 = 31598282

Showing the first eight; more decompositions exist.
