Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538040, here are decompositions:

13 + 33538027 = 33538040
31 + 33538009 = 33538040
37 + 33538003 = 33538040
79 + 33537961 = 33538040
271 + 33537769 = 33538040
331 + 33537709 = 33538040
499 + 33537541 = 33538040
607 + 33537433 = 33538040

Showing the first eight; more decompositions exist.
