Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496130, here are decompositions:

7 + 31496123 = 31496130
11 + 31496119 = 31496130
31 + 31496099 = 31496130
47 + 31496083 = 31496130
73 + 31496057 = 31496130
89 + 31496041 = 31496130
103 + 31496027 = 31496130
151 + 31495979 = 31496130

Showing the first eight; more decompositions exist.
