Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531448, here are decompositions:

17 + 33531431 = 33531448
59 + 33531389 = 33531448
101 + 33531347 = 33531448
149 + 33531299 = 33531448
179 + 33531269 = 33531448
281 + 33531167 = 33531448
389 + 33531059 = 33531448
449 + 33530999 = 33531448

Showing the first eight; more decompositions exist.
