Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599898, here are decompositions:

89 + 31599809 = 31599898
131 + 31599767 = 31599898
137 + 31599761 = 31599898
191 + 31599707 = 31599898
227 + 31599671 = 31599898
269 + 31599629 = 31599898
347 + 31599551 = 31599898
467 + 31599431 = 31599898

Showing the first eight; more decompositions exist.
