Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506124, here are decompositions:

5 + 31506119 = 31506124
53 + 31506071 = 31506124
131 + 31505993 = 31506124
197 + 31505927 = 31506124
281 + 31505843 = 31506124
311 + 31505813 = 31506124
317 + 31505807 = 31506124
383 + 31505741 = 31506124

Showing the first eight; more decompositions exist.
