Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478144, here are decompositions:

17 + 33478127 = 33478144
23 + 33478121 = 33478144
47 + 33478097 = 33478144
83 + 33478061 = 33478144
131 + 33478013 = 33478144
173 + 33477971 = 33478144
263 + 33477881 = 33478144
431 + 33477713 = 33478144

Showing the first eight; more decompositions exist.
