Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619926, here are decompositions:

83 + 31619843 = 31619926
137 + 31619789 = 31619926
167 + 31619759 = 31619926
257 + 31619669 = 31619926
383 + 31619543 = 31619926
467 + 31619459 = 31619926
599 + 31619327 = 31619926
659 + 31619267 = 31619926

Showing the first eight; more decompositions exist.
