Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598838, here are decompositions:

59 + 31598779 = 31598838
67 + 31598771 = 31598838
137 + 31598701 = 31598838
151 + 31598687 = 31598838
191 + 31598647 = 31598838
317 + 31598521 = 31598838
379 + 31598459 = 31598838
389 + 31598449 = 31598838

Showing the first eight; more decompositions exist.
