Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73800, here are decompositions:
- 17 + 73783 = 73800
- 29 + 73771 = 73800
- 43 + 73757 = 73800
- 73 + 73727 = 73800
- 79 + 73721 = 73800
- 101 + 73699 = 73800
- 107 + 73693 = 73800
- 127 + 73673 = 73800
Showing the first eight; more decompositions exist.
