Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559102, here are decompositions:

31 + 31559071 = 31559102
109 + 31558993 = 31559102
139 + 31558963 = 31559102
163 + 31558939 = 31559102
271 + 31558831 = 31559102
283 + 31558819 = 31559102
313 + 31558789 = 31559102
331 + 31558771 = 31559102

Showing the first eight; more decompositions exist.
