Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559174, here are decompositions:

13 + 31559161 = 31559174
43 + 31559131 = 31559174
103 + 31559071 = 31559174
181 + 31558993 = 31559174
211 + 31558963 = 31559174
277 + 31558897 = 31559174
331 + 31558843 = 31559174
433 + 31558741 = 31559174

Showing the first eight; more decompositions exist.
