Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487370, here are decompositions:

61 + 33487309 = 33487370
97 + 33487273 = 33487370
109 + 33487261 = 33487370
151 + 33487219 = 33487370
181 + 33487189 = 33487370
223 + 33487147 = 33487370
337 + 33487033 = 33487370
349 + 33487021 = 33487370

Showing the first eight; more decompositions exist.
