Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478172, here are decompositions:

3 + 33478169 = 33478172
19 + 33478153 = 33478172
61 + 33478111 = 33478172
109 + 33478063 = 33478172
163 + 33478009 = 33478172
241 + 33477931 = 33478172
379 + 33477793 = 33478172
523 + 33477649 = 33478172

Showing the first eight; more decompositions exist.
