Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487838, here are decompositions:

19 + 33487819 = 33487838
67 + 33487771 = 33487838
79 + 33487759 = 33487838
157 + 33487681 = 33487838
199 + 33487639 = 33487838
277 + 33487561 = 33487838
331 + 33487507 = 33487838
421 + 33487417 = 33487838

Showing the first eight; more decompositions exist.
