Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79890, here are decompositions:
- 17 + 79873 = 79890
- 23 + 79867 = 79890
- 29 + 79861 = 79890
- 43 + 79847 = 79890
- 47 + 79843 = 79890
- 61 + 79829 = 79890
- 67 + 79823 = 79890
- 73 + 79817 = 79890
Showing the first eight; more decompositions exist.
