Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33622778, here are decompositions:

157 + 33622621 = 33622778
307 + 33622471 = 33622778
337 + 33622441 = 33622778
349 + 33622429 = 33622778
367 + 33622411 = 33622778
379 + 33622399 = 33622778
421 + 33622357 = 33622778
499 + 33622279 = 33622778

Showing the first eight; more decompositions exist.
