Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488540, here are decompositions:

3 + 33488537 = 33488540
31 + 33488509 = 33488540
61 + 33488479 = 33488540
73 + 33488467 = 33488540
79 + 33488461 = 33488540
229 + 33488311 = 33488540
373 + 33488167 = 33488540
409 + 33488131 = 33488540

Showing the first eight; more decompositions exist.
