Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561990, here are decompositions:
- 13 + 33561977 = 33561990
- 31 + 33561959 = 33561990
- 37 + 33561953 = 33561990
- 41 + 33561949 = 33561990
- 47 + 33561943 = 33561990
- 61 + 33561929 = 33561990
- 71 + 33561919 = 33561990
- 73 + 33561917 = 33561990
Showing the first eight; more decompositions exist.
