Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487994, here are decompositions:

181 + 33487813 = 33487994
223 + 33487771 = 33487994
277 + 33487717 = 33487994
313 + 33487681 = 33487994
373 + 33487621 = 33487994
433 + 33487561 = 33487994
457 + 33487537 = 33487994
487 + 33487507 = 33487994

Showing the first eight; more decompositions exist.
