Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533802, here are decompositions:

11 + 31533791 = 31533802
29 + 31533773 = 31533802
191 + 31533611 = 31533802
239 + 31533563 = 31533802
269 + 31533533 = 31533802
353 + 31533449 = 31533802
389 + 31533413 = 31533802
431 + 31533371 = 31533802

Showing the first eight; more decompositions exist.
