Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557530, here are decompositions:

59 + 33557471 = 33557530
101 + 33557429 = 33557530
107 + 33557423 = 33557530
113 + 33557417 = 33557530
131 + 33557399 = 33557530
173 + 33557357 = 33557530
191 + 33557339 = 33557530
443 + 33557087 = 33557530

Showing the first eight; more decompositions exist.
