Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536082, here are decompositions:

29 + 31536053 = 31536082
101 + 31535981 = 31536082
173 + 31535909 = 31536082
251 + 31535831 = 31536082
401 + 31535681 = 31536082
443 + 31535639 = 31536082
449 + 31535633 = 31536082
491 + 31535591 = 31536082

Showing the first eight; more decompositions exist.
