Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598122, here are decompositions:

89 + 31598033 = 31598122
113 + 31598009 = 31598122
359 + 31597763 = 31598122
383 + 31597739 = 31598122
401 + 31597721 = 31598122
449 + 31597673 = 31598122
509 + 31597613 = 31598122
839 + 31597283 = 31598122

Showing the first eight; more decompositions exist.
