Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598192, here are decompositions:

13 + 31598179 = 31598192
163 + 31598029 = 31598192
181 + 31598011 = 31598192
313 + 31597879 = 31598192
349 + 31597843 = 31598192
463 + 31597729 = 31598192
499 + 31597693 = 31598192
541 + 31597651 = 31598192

Showing the first eight; more decompositions exist.
