Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600082, here are decompositions:

43 + 31600039 = 31600082
181 + 31599901 = 31600082
211 + 31599871 = 31600082
223 + 31599859 = 31600082
271 + 31599811 = 31600082
379 + 31599703 = 31600082
433 + 31599649 = 31600082
643 + 31599439 = 31600082

Showing the first eight; more decompositions exist.
