Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621672, here are decompositions:
- 11 + 33621661 = 33621672
- 23 + 33621649 = 33621672
- 43 + 33621629 = 33621672
- 61 + 33621611 = 33621672
- 79 + 33621593 = 33621672
- 113 + 33621559 = 33621672
- 131 + 33621541 = 33621672
- 181 + 33621491 = 33621672
Showing the first eight; more decompositions exist.
