Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487868, here are decompositions:

97 + 33487771 = 33487868
109 + 33487759 = 33487868
151 + 33487717 = 33487868
229 + 33487639 = 33487868
277 + 33487591 = 33487868
307 + 33487561 = 33487868
331 + 33487537 = 33487868
607 + 33487261 = 33487868

Showing the first eight; more decompositions exist.
