Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72824, here are decompositions:
- 7 + 72817 = 72824
- 61 + 72763 = 72824
- 97 + 72727 = 72824
- 151 + 72673 = 72824
- 163 + 72661 = 72824
- 181 + 72643 = 72824
- 211 + 72613 = 72824
- 277 + 72547 = 72824
Showing the first eight; more decompositions exist.
