Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599042, here are decompositions:

53 + 31598989 = 31599042
89 + 31598953 = 31599042
103 + 31598939 = 31599042
109 + 31598933 = 31599042
131 + 31598911 = 31599042
179 + 31598863 = 31599042
263 + 31598779 = 31599042
271 + 31598771 = 31599042

Showing the first eight; more decompositions exist.
