Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600232, here are decompositions:

31 + 31600201 = 31600232
43 + 31600189 = 31600232
193 + 31600039 = 31600232
331 + 31599901 = 31600232
373 + 31599859 = 31600232
409 + 31599823 = 31600232
421 + 31599811 = 31600232
733 + 31599499 = 31600232

Showing the first eight; more decompositions exist.
