Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487398, here are decompositions:

5 + 33487393 = 33487398
11 + 33487387 = 33487398
79 + 33487319 = 33487398
89 + 33487309 = 33487398
97 + 33487301 = 33487398
127 + 33487271 = 33487398
137 + 33487261 = 33487398
151 + 33487247 = 33487398

Showing the first eight; more decompositions exist.
