Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487874, here are decompositions:

61 + 33487813 = 33487874
103 + 33487771 = 33487874
157 + 33487717 = 33487874
193 + 33487681 = 33487874
223 + 33487651 = 33487874
283 + 33487591 = 33487874
313 + 33487561 = 33487874
331 + 33487543 = 33487874

Showing the first eight; more decompositions exist.
