Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79990, here are decompositions:
- 3 + 79987 = 79990
- 11 + 79979 = 79990
- 17 + 79973 = 79990
- 23 + 79967 = 79990
- 47 + 79943 = 79990
- 83 + 79907 = 79990
- 89 + 79901 = 79990
- 101 + 79889 = 79990
Showing the first eight; more decompositions exist.
