Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587978, here are decompositions:

37 + 33587941 = 33587978
241 + 33587737 = 33587978
271 + 33587707 = 33587978
331 + 33587647 = 33587978
397 + 33587581 = 33587978
421 + 33587557 = 33587978
499 + 33587479 = 33587978
577 + 33587401 = 33587978

Showing the first eight; more decompositions exist.
