Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559084, here are decompositions:

3 + 31559081 = 31559084
13 + 31559071 = 31559084
127 + 31558957 = 31559084
157 + 31558927 = 31559084
241 + 31558843 = 31559084
313 + 31558771 = 31559084
367 + 31558717 = 31559084
421 + 31558663 = 31559084

Showing the first eight; more decompositions exist.
