Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538700, here are decompositions:

37 + 33538663 = 33538700
61 + 33538639 = 33538700
67 + 33538633 = 33538700
73 + 33538627 = 33538700
157 + 33538543 = 33538700
193 + 33538507 = 33538700
313 + 33538387 = 33538700
373 + 33538327 = 33538700

Showing the first eight; more decompositions exist.
