Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488640, here are decompositions:
- 13 + 33488627 = 33488640
- 41 + 33488599 = 33488640
- 47 + 33488593 = 33488640
- 71 + 33488569 = 33488640
- 83 + 33488557 = 33488640
- 103 + 33488537 = 33488640
- 131 + 33488509 = 33488640
- 139 + 33488501 = 33488640
Showing the first eight; more decompositions exist.
