Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537890, here are decompositions:

181 + 33537709 = 33537890
277 + 33537613 = 33537890
349 + 33537541 = 33537890
367 + 33537523 = 33537890
457 + 33537433 = 33537890
577 + 33537313 = 33537890
691 + 33537199 = 33537890
769 + 33537121 = 33537890

Showing the first eight; more decompositions exist.
