Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463286, here are decompositions:

5 + 31463281 = 31463286
17 + 31463269 = 31463286
37 + 31463249 = 31463286
59 + 31463227 = 31463286
73 + 31463213 = 31463286
83 + 31463203 = 31463286
89 + 31463197 = 31463286
139 + 31463147 = 31463286

Showing the first eight; more decompositions exist.
