Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477440, here are decompositions:

103 + 33477337 = 33477440
109 + 33477331 = 33477440
127 + 33477313 = 33477440
193 + 33477247 = 33477440
229 + 33477211 = 33477440
397 + 33477043 = 33477440
463 + 33476977 = 33477440
499 + 33476941 = 33477440

Showing the first eight; more decompositions exist.
