Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599048, here are decompositions:

59 + 31598989 = 31599048
101 + 31598947 = 31599048
109 + 31598939 = 31599048
137 + 31598911 = 31599048
139 + 31598909 = 31599048
181 + 31598867 = 31599048
191 + 31598857 = 31599048
269 + 31598779 = 31599048

Showing the first eight; more decompositions exist.
