Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598132, here are decompositions:

31 + 31598101 = 31598132
103 + 31598029 = 31598132
199 + 31597933 = 31598132
331 + 31597801 = 31598132
439 + 31597693 = 31598132
661 + 31597471 = 31598132
919 + 31597213 = 31598132
1033 + 31597099 = 31598132

Showing the first eight; more decompositions exist.
