Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80100, here are decompositions:
- 23 + 80077 = 80100
- 29 + 80071 = 80100
- 61 + 80039 = 80100
- 79 + 80021 = 80100
- 101 + 79999 = 80100
- 103 + 79997 = 80100
- 113 + 79987 = 80100
- 127 + 79973 = 80100
Showing the first eight; more decompositions exist.
