Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487886, here are decompositions:

67 + 33487819 = 33487886
73 + 33487813 = 33487886
127 + 33487759 = 33487886
307 + 33487579 = 33487886
349 + 33487537 = 33487886
373 + 33487513 = 33487886
379 + 33487507 = 33487886
409 + 33487477 = 33487886

Showing the first eight; more decompositions exist.
