Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506106, here are decompositions:

3 + 31506103 = 31506106
113 + 31505993 = 31506106
167 + 31505939 = 31506106
179 + 31505927 = 31506106
197 + 31505909 = 31506106
263 + 31505843 = 31506106
293 + 31505813 = 31506106
383 + 31505723 = 31506106

Showing the first eight; more decompositions exist.
