Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487686, here are decompositions:

5 + 33487681 = 33487686
47 + 33487639 = 33487686
79 + 33487607 = 33487686
107 + 33487579 = 33487686
149 + 33487537 = 33487686
173 + 33487513 = 33487686
179 + 33487507 = 33487686
263 + 33487423 = 33487686

Showing the first eight; more decompositions exist.
