Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598162, here are decompositions:

19 + 31598143 = 31598162
61 + 31598101 = 31598162
151 + 31598011 = 31598162
229 + 31597933 = 31598162
283 + 31597879 = 31598162
433 + 31597729 = 31598162
523 + 31597639 = 31598162
613 + 31597549 = 31598162

Showing the first eight; more decompositions exist.
