Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559626, here are decompositions:

3 + 31559623 = 31559626
53 + 31559573 = 31559626
89 + 31559537 = 31559626
179 + 31559447 = 31559626
419 + 31559207 = 31559626
557 + 31559069 = 31559626
599 + 31559027 = 31559626
653 + 31558973 = 31559626

Showing the first eight; more decompositions exist.
