Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491742, here are decompositions:

13 + 33491729 = 33491742
23 + 33491719 = 33491742
29 + 33491713 = 33491742
61 + 33491681 = 33491742
71 + 33491671 = 33491742
101 + 33491641 = 33491742
103 + 33491639 = 33491742
139 + 33491603 = 33491742

Showing the first eight; more decompositions exist.
