Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537580, here are decompositions:

23 + 33537557 = 33537580
29 + 33537551 = 33537580
71 + 33537509 = 33537580
191 + 33537389 = 33537580
317 + 33537263 = 33537580
347 + 33537233 = 33537580
353 + 33537227 = 33537580
389 + 33537191 = 33537580

Showing the first eight; more decompositions exist.
