Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481196, here are decompositions:

7 + 31481189 = 31481196
17 + 31481179 = 31481196
37 + 31481159 = 31481196
53 + 31481143 = 31481196
73 + 31481123 = 31481196
83 + 31481113 = 31481196
139 + 31481057 = 31481196
157 + 31481039 = 31481196

Showing the first eight; more decompositions exist.
