Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507642, here are decompositions:

11 + 33507631 = 33507642
19 + 33507623 = 33507642
31 + 33507611 = 33507642
41 + 33507601 = 33507642
43 + 33507599 = 33507642
79 + 33507563 = 33507642
101 + 33507541 = 33507642
139 + 33507503 = 33507642

Showing the first eight; more decompositions exist.
