Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559254, here are decompositions:

3 + 31559251 = 31559254
47 + 31559207 = 31559254
173 + 31559081 = 31559254
227 + 31559027 = 31559254
257 + 31558997 = 31559254
281 + 31558973 = 31559254
431 + 31558823 = 31559254
521 + 31558733 = 31559254

Showing the first eight; more decompositions exist.
