Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488890, here are decompositions:

23 + 33488867 = 33488890
53 + 33488837 = 33488890
101 + 33488789 = 33488890
173 + 33488717 = 33488890
251 + 33488639 = 33488890
263 + 33488627 = 33488890
353 + 33488537 = 33488890
389 + 33488501 = 33488890

Showing the first eight; more decompositions exist.
