Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488578, here are decompositions:

29 + 33488549 = 33488578
41 + 33488537 = 33488578
107 + 33488471 = 33488578
197 + 33488381 = 33488578
269 + 33488309 = 33488578
491 + 33488087 = 33488578
677 + 33487901 = 33488578
701 + 33487877 = 33488578

Showing the first eight; more decompositions exist.
