Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491646, here are decompositions:

5 + 33491641 = 33491646
7 + 33491639 = 33491646
43 + 33491603 = 33491646
47 + 33491599 = 33491646
53 + 33491593 = 33491646
79 + 33491567 = 33491646
103 + 33491543 = 33491646
109 + 33491537 = 33491646

Showing the first eight; more decompositions exist.
