Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599782, here are decompositions:

79 + 31599703 = 31599782
229 + 31599553 = 31599782
283 + 31599499 = 31599782
433 + 31599349 = 31599782
523 + 31599259 = 31599782
829 + 31598953 = 31599782
859 + 31598923 = 31599782
919 + 31598863 = 31599782

Showing the first eight; more decompositions exist.
