Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559702, here are decompositions:

3 + 31559699 = 31559702
43 + 31559659 = 31559702
61 + 31559641 = 31559702
79 + 31559623 = 31559702
331 + 31559371 = 31559702
439 + 31559263 = 31559702
463 + 31559239 = 31559702
541 + 31559161 = 31559702

Showing the first eight; more decompositions exist.
