Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599012, here are decompositions:

23 + 31598989 = 31599012
59 + 31598953 = 31599012
73 + 31598939 = 31599012
79 + 31598933 = 31599012
89 + 31598923 = 31599012
101 + 31598911 = 31599012
103 + 31598909 = 31599012
139 + 31598873 = 31599012

Showing the first eight; more decompositions exist.
