Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536658, here are decompositions:

29 + 31536629 = 31536658
107 + 31536551 = 31536658
137 + 31536521 = 31536658
311 + 31536347 = 31536658
431 + 31536227 = 31536658
557 + 31536101 = 31536658
641 + 31536017 = 31536658
677 + 31535981 = 31536658

Showing the first eight; more decompositions exist.
