Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620740, here are decompositions:

59 + 33620681 = 33620740
113 + 33620627 = 33620740
149 + 33620591 = 33620740
227 + 33620513 = 33620740
233 + 33620507 = 33620740
269 + 33620471 = 33620740
281 + 33620459 = 33620740
311 + 33620429 = 33620740

Showing the first eight; more decompositions exist.
