Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507578, here are decompositions:

37 + 33507541 = 33507578
199 + 33507379 = 33507578
271 + 33507307 = 33507578
331 + 33507247 = 33507578
367 + 33507211 = 33507578
457 + 33507121 = 33507578
499 + 33507079 = 33507578
541 + 33507037 = 33507578

Showing the first eight; more decompositions exist.
