Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536558, here are decompositions:

7 + 31536551 = 31536558
19 + 31536539 = 31536558
29 + 31536529 = 31536558
37 + 31536521 = 31536558
59 + 31536499 = 31536558
167 + 31536391 = 31536558
197 + 31536361 = 31536558
199 + 31536359 = 31536558

Showing the first eight; more decompositions exist.
