Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621742, here are decompositions:

29 + 33621713 = 33621742
113 + 33621629 = 33621742
131 + 33621611 = 33621742
149 + 33621593 = 33621742
251 + 33621491 = 33621742
269 + 33621473 = 33621742
353 + 33621389 = 33621742
359 + 33621383 = 33621742

Showing the first eight; more decompositions exist.
