Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79872, here are decompositions:
- 5 + 79867 = 79872
- 11 + 79861 = 79872
- 29 + 79843 = 79872
- 31 + 79841 = 79872
- 43 + 79829 = 79872
- 59 + 79813 = 79872
- 61 + 79811 = 79872
- 71 + 79801 = 79872
Showing the first eight; more decompositions exist.
