Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599464, here are decompositions:

151 + 31599313 = 31599464
157 + 31599307 = 31599464
271 + 31599193 = 31599464
307 + 31599157 = 31599464
541 + 31598923 = 31599464
577 + 31598887 = 31599464
601 + 31598863 = 31599464
607 + 31598857 = 31599464

Showing the first eight; more decompositions exist.
