Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600016, here are decompositions:

103 + 31599913 = 31600016
139 + 31599877 = 31600016
157 + 31599859 = 31600016
193 + 31599823 = 31600016
313 + 31599703 = 31600016
367 + 31599649 = 31600016
463 + 31599553 = 31600016
577 + 31599439 = 31600016

Showing the first eight; more decompositions exist.
