Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487680, here are decompositions:

29 + 33487651 = 33487680
41 + 33487639 = 33487680
59 + 33487621 = 33487680
73 + 33487607 = 33487680
89 + 33487591 = 33487680
101 + 33487579 = 33487680
137 + 33487543 = 33487680
167 + 33487513 = 33487680

Showing the first eight; more decompositions exist.
