Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33390, here are decompositions:
- 13 + 33377 = 33390
- 31 + 33359 = 33390
- 37 + 33353 = 33390
- 41 + 33349 = 33390
- 43 + 33347 = 33390
- 47 + 33343 = 33390
- 59 + 33331 = 33390
- 61 + 33329 = 33390
Showing the first eight; more decompositions exist.
