Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536938, here are decompositions:

67 + 31536871 = 31536938
109 + 31536829 = 31536938
241 + 31536697 = 31536938
331 + 31536607 = 31536938
409 + 31536529 = 31536938
439 + 31536499 = 31536938
457 + 31536481 = 31536938
541 + 31536397 = 31536938

Showing the first eight; more decompositions exist.
