Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559264, here are decompositions:

13 + 31559251 = 31559264
103 + 31559161 = 31559264
193 + 31559071 = 31559264
271 + 31558993 = 31559264
307 + 31558957 = 31559264
337 + 31558927 = 31559264
367 + 31558897 = 31559264
421 + 31558843 = 31559264

Showing the first eight; more decompositions exist.
