Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600070, here are decompositions:

13 + 31600057 = 31600070
31 + 31600039 = 31600070
157 + 31599913 = 31600070
193 + 31599877 = 31600070
199 + 31599871 = 31600070
211 + 31599859 = 31600070
367 + 31599703 = 31600070
421 + 31599649 = 31600070

Showing the first eight; more decompositions exist.
