Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79854, here are decompositions:
- 7 + 79847 = 79854
- 11 + 79843 = 79854
- 13 + 79841 = 79854
- 31 + 79823 = 79854
- 37 + 79817 = 79854
- 41 + 79813 = 79854
- 43 + 79811 = 79854
- 53 + 79801 = 79854
Showing the first eight; more decompositions exist.
