Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939624, here are decompositions:
- 11 + 939613 = 939624
- 13 + 939611 = 939624
- 43 + 939581 = 939624
- 73 + 939551 = 939624
- 113 + 939511 = 939624
- 137 + 939487 = 939624
- 173 + 939451 = 939624
- 181 + 939443 = 939624
Showing the first eight; more decompositions exist.
