Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600392, here are decompositions:

59 + 31600333 = 31600392
73 + 31600319 = 31600392
101 + 31600291 = 31600392
113 + 31600279 = 31600392
191 + 31600201 = 31600392
199 + 31600193 = 31600392
293 + 31600099 = 31600392
331 + 31600061 = 31600392

Showing the first eight; more decompositions exist.
