Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80102, here are decompositions:
- 31 + 80071 = 80102
- 103 + 79999 = 80102
- 163 + 79939 = 80102
- 199 + 79903 = 80102
- 229 + 79873 = 80102
- 241 + 79861 = 80102
- 409 + 79693 = 80102
- 433 + 79669 = 80102
Showing the first eight; more decompositions exist.
