Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560246, here are decompositions:

7 + 31560239 = 31560246
13 + 31560233 = 31560246
19 + 31560227 = 31560246
73 + 31560173 = 31560246
139 + 31560107 = 31560246
149 + 31560097 = 31560246
167 + 31560079 = 31560246
173 + 31560073 = 31560246

Showing the first eight; more decompositions exist.
