Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536452, here are decompositions:

61 + 31536391 = 31536452
139 + 31536313 = 31536452
229 + 31536223 = 31536452
433 + 31536019 = 31536452
631 + 31535821 = 31536452
643 + 31535809 = 31536452
859 + 31535593 = 31536452
1033 + 31535419 = 31536452

Showing the first eight; more decompositions exist.
