Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518780, here are decompositions:

13 + 33518767 = 33518780
103 + 33518677 = 33518780
157 + 33518623 = 33518780
193 + 33518587 = 33518780
241 + 33518539 = 33518780
283 + 33518497 = 33518780
331 + 33518449 = 33518780
487 + 33518293 = 33518780

Showing the first eight; more decompositions exist.
