Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488742, here are decompositions:

13 + 33488729 = 33488742
59 + 33488683 = 33488742
61 + 33488681 = 33488742
73 + 33488669 = 33488742
103 + 33488639 = 33488742
149 + 33488593 = 33488742
173 + 33488569 = 33488742
193 + 33488549 = 33488742

Showing the first eight; more decompositions exist.
