Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72876, here are decompositions:
- 5 + 72871 = 72876
- 7 + 72869 = 72876
- 17 + 72859 = 72876
- 53 + 72823 = 72876
- 59 + 72817 = 72876
- 79 + 72797 = 72876
- 109 + 72767 = 72876
- 113 + 72763 = 72876
Showing the first eight; more decompositions exist.
