Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481302, here are decompositions:

3 + 31481299 = 31481302
53 + 31481249 = 31481302
71 + 31481231 = 31481302
101 + 31481201 = 31481302
113 + 31481189 = 31481302
131 + 31481171 = 31481302
179 + 31481123 = 31481302
191 + 31481111 = 31481302

Showing the first eight; more decompositions exist.
