Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533468, here are decompositions:

7 + 31533461 = 31533468
17 + 31533451 = 31533468
19 + 31533449 = 31533468
37 + 31533431 = 31533468
59 + 31533409 = 31533468
79 + 31533389 = 31533468
89 + 31533379 = 31533468
97 + 31533371 = 31533468

Showing the first eight; more decompositions exist.
