Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598228, here are decompositions:

37 + 31598191 = 31598228
127 + 31598101 = 31598228
199 + 31598029 = 31598228
241 + 31597987 = 31598228
349 + 31597879 = 31598228
499 + 31597729 = 31598228
577 + 31597651 = 31598228
757 + 31597471 = 31598228

Showing the first eight; more decompositions exist.
