Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478140, here are decompositions:

13 + 33478127 = 33478140
19 + 33478121 = 33478140
29 + 33478111 = 33478140
43 + 33478097 = 33478140
61 + 33478079 = 33478140
79 + 33478061 = 33478140
127 + 33478013 = 33478140
131 + 33478009 = 33478140

Showing the first eight; more decompositions exist.
