Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544642, here are decompositions:

3 + 33544639 = 33544642
11 + 33544631 = 33544642
29 + 33544613 = 33544642
59 + 33544583 = 33544642
101 + 33544541 = 33544642
149 + 33544493 = 33544642
311 + 33544331 = 33544642
419 + 33544223 = 33544642

Showing the first eight; more decompositions exist.
