Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533474, here are decompositions:

13 + 31533461 = 31533474
23 + 31533451 = 31533474
43 + 31533431 = 31533474
61 + 31533413 = 31533474
103 + 31533371 = 31533474
131 + 31533343 = 31533474
283 + 31533191 = 31533474
307 + 31533167 = 31533474

Showing the first eight; more decompositions exist.
