Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99780, here are decompositions:
- 13 + 99767 = 99780
- 19 + 99761 = 99780
- 47 + 99733 = 99780
- 59 + 99721 = 99780
- 61 + 99719 = 99780
- 67 + 99713 = 99780
- 71 + 99709 = 99780
- 73 + 99707 = 99780
Showing the first eight; more decompositions exist.
