Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581258, here are decompositions:

37 + 33581221 = 33581258
127 + 33581131 = 33581258
349 + 33580909 = 33581258
367 + 33580891 = 33581258
379 + 33580879 = 33581258
409 + 33580849 = 33581258
439 + 33580819 = 33581258
457 + 33580801 = 33581258

Showing the first eight; more decompositions exist.
