Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478242, here are decompositions:

11 + 33478231 = 33478242
41 + 33478201 = 33478242
43 + 33478199 = 33478242
53 + 33478189 = 33478242
59 + 33478183 = 33478242
73 + 33478169 = 33478242
79 + 33478163 = 33478242
89 + 33478153 = 33478242

Showing the first eight; more decompositions exist.
