Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79810, here are decompositions:
- 41 + 79769 = 79810
- 53 + 79757 = 79810
- 113 + 79697 = 79810
- 179 + 79631 = 79810
- 197 + 79613 = 79810
- 251 + 79559 = 79810
- 317 + 79493 = 79810
- 359 + 79451 = 79810
Showing the first eight; more decompositions exist.
