Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559412, here are decompositions:

11 + 31559401 = 31559412
29 + 31559383 = 31559412
41 + 31559371 = 31559412
61 + 31559351 = 31559412
149 + 31559263 = 31559412
173 + 31559239 = 31559412
193 + 31559219 = 31559412
223 + 31559189 = 31559412

Showing the first eight; more decompositions exist.
