Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506076, here are decompositions:

5 + 31506071 = 31506076
47 + 31506029 = 31506076
83 + 31505993 = 31506076
137 + 31505939 = 31506076
149 + 31505927 = 31506076
167 + 31505909 = 31506076
233 + 31505843 = 31506076
263 + 31505813 = 31506076

Showing the first eight; more decompositions exist.
