Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536744, here are decompositions:

11 + 31536733 = 31536744
13 + 31536731 = 31536744
37 + 31536707 = 31536744
47 + 31536697 = 31536744
131 + 31536613 = 31536744
137 + 31536607 = 31536744
193 + 31536551 = 31536744
223 + 31536521 = 31536744

Showing the first eight; more decompositions exist.
