Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599026, here are decompositions:

37 + 31598989 = 31599026
73 + 31598953 = 31599026
79 + 31598947 = 31599026
103 + 31598923 = 31599026
139 + 31598887 = 31599026
163 + 31598863 = 31599026
379 + 31598647 = 31599026
577 + 31598449 = 31599026

Showing the first eight; more decompositions exist.
