Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79988, here are decompositions:
- 127 + 79861 = 79988
- 211 + 79777 = 79988
- 331 + 79657 = 79988
- 367 + 79621 = 79988
- 379 + 79609 = 79988
- 409 + 79579 = 79988
- 439 + 79549 = 79988
- 457 + 79531 = 79988
Showing the first eight; more decompositions exist.
