Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487646, here are decompositions:

7 + 33487639 = 33487646
67 + 33487579 = 33487646
103 + 33487543 = 33487646
109 + 33487537 = 33487646
139 + 33487507 = 33487646
223 + 33487423 = 33487646
229 + 33487417 = 33487646
337 + 33487309 = 33487646

Showing the first eight; more decompositions exist.
