Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478520, here are decompositions:

3 + 33478517 = 33478520
43 + 33478477 = 33478520
109 + 33478411 = 33478520
331 + 33478189 = 33478520
337 + 33478183 = 33478520
367 + 33478153 = 33478520
409 + 33478111 = 33478520
457 + 33478063 = 33478520

Showing the first eight; more decompositions exist.
