Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595798, here are decompositions:

67 + 31595731 = 31595798
79 + 31595719 = 31595798
97 + 31595701 = 31595798
127 + 31595671 = 31595798
229 + 31595569 = 31595798
331 + 31595467 = 31595798
547 + 31595251 = 31595798
739 + 31595059 = 31595798

Showing the first eight; more decompositions exist.
