Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531612, here are decompositions:

53 + 33531559 = 33531612
71 + 33531541 = 33531612
109 + 33531503 = 33531612
113 + 33531499 = 33531612
139 + 33531473 = 33531612
173 + 33531439 = 33531612
181 + 33531431 = 33531612
199 + 33531413 = 33531612

Showing the first eight; more decompositions exist.
