Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600444, here are decompositions:

3 + 31600441 = 31600444
23 + 31600421 = 31600444
137 + 31600307 = 31600444
167 + 31600277 = 31600444
251 + 31600193 = 31600444
311 + 31600133 = 31600444
383 + 31600061 = 31600444
401 + 31600043 = 31600444

Showing the first eight; more decompositions exist.
