Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559534, here are decompositions:

67 + 31559467 = 31559534
151 + 31559383 = 31559534
163 + 31559371 = 31559534
271 + 31559263 = 31559534
283 + 31559251 = 31559534
373 + 31559161 = 31559534
463 + 31559071 = 31559534
541 + 31558993 = 31559534

Showing the first eight; more decompositions exist.
