Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478158, here are decompositions:

5 + 33478153 = 33478158
31 + 33478127 = 33478158
37 + 33478121 = 33478158
47 + 33478111 = 33478158
61 + 33478097 = 33478158
79 + 33478079 = 33478158
97 + 33478061 = 33478158
149 + 33478009 = 33478158

Showing the first eight; more decompositions exist.
