Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625640, here are decompositions:

73 + 33625567 = 33625640
79 + 33625561 = 33625640
127 + 33625513 = 33625640
163 + 33625477 = 33625640
193 + 33625447 = 33625640
211 + 33625429 = 33625640
229 + 33625411 = 33625640
271 + 33625369 = 33625640

Showing the first eight; more decompositions exist.
