Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487650, here are decompositions:

11 + 33487639 = 33487650
19 + 33487631 = 33487650
29 + 33487621 = 33487650
43 + 33487607 = 33487650
59 + 33487591 = 33487650
71 + 33487579 = 33487650
89 + 33487561 = 33487650
107 + 33487543 = 33487650

Showing the first eight; more decompositions exist.
