Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559324, here are decompositions:

3 + 31559321 = 31559324
7 + 31559317 = 31559324
61 + 31559263 = 31559324
73 + 31559251 = 31559324
163 + 31559161 = 31559324
193 + 31559131 = 31559324
331 + 31558993 = 31559324
367 + 31558957 = 31559324

Showing the first eight; more decompositions exist.
