Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600040, here are decompositions:

127 + 31599913 = 31600040
139 + 31599901 = 31600040
163 + 31599877 = 31600040
181 + 31599859 = 31600040
229 + 31599811 = 31600040
313 + 31599727 = 31600040
337 + 31599703 = 31600040
487 + 31599553 = 31600040

Showing the first eight; more decompositions exist.
