Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600244, here are decompositions:

43 + 31600201 = 31600244
127 + 31600117 = 31600244
157 + 31600087 = 31600244
331 + 31599913 = 31600244
367 + 31599877 = 31600244
373 + 31599871 = 31600244
421 + 31599823 = 31600244
433 + 31599811 = 31600244

Showing the first eight; more decompositions exist.
