Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536344, here are decompositions:

31 + 31536313 = 31536344
157 + 31536187 = 31536344
283 + 31536061 = 31536344
397 + 31535947 = 31536344
523 + 31535821 = 31536344
547 + 31535797 = 31536344
673 + 31535671 = 31536344
751 + 31535593 = 31536344

Showing the first eight; more decompositions exist.
