Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600142, here are decompositions:

43 + 31600099 = 31600142
103 + 31600039 = 31600142
229 + 31599913 = 31600142
241 + 31599901 = 31600142
271 + 31599871 = 31600142
283 + 31599859 = 31600142
331 + 31599811 = 31600142
439 + 31599703 = 31600142

Showing the first eight; more decompositions exist.
