Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598212, here are decompositions:

11 + 31598201 = 31598212
71 + 31598141 = 31598212
179 + 31598033 = 31598212
251 + 31597961 = 31598212
389 + 31597823 = 31598212
419 + 31597793 = 31598212
449 + 31597763 = 31598212
491 + 31597721 = 31598212

Showing the first eight; more decompositions exist.
