Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600242, here are decompositions:

41 + 31600201 = 31600242
53 + 31600189 = 31600242
109 + 31600133 = 31600242
139 + 31600103 = 31600242
181 + 31600061 = 31600242
199 + 31600043 = 31600242
241 + 31600001 = 31600242
283 + 31599959 = 31600242

Showing the first eight; more decompositions exist.
