Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536426, here are decompositions:

23 + 31536403 = 31536426
29 + 31536397 = 31536426
43 + 31536383 = 31536426
67 + 31536359 = 31536426
73 + 31536353 = 31536426
79 + 31536347 = 31536426
113 + 31536313 = 31536426
139 + 31536287 = 31536426

Showing the first eight; more decompositions exist.
