Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559498, here are decompositions:

31 + 31559467 = 31559498
97 + 31559401 = 31559498
127 + 31559371 = 31559498
181 + 31559317 = 31559498
337 + 31559161 = 31559498
349 + 31559149 = 31559498
367 + 31559131 = 31559498
541 + 31558957 = 31559498

Showing the first eight; more decompositions exist.
