Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72924, here are decompositions:
- 13 + 72911 = 72924
- 17 + 72907 = 72924
- 23 + 72901 = 72924
- 31 + 72893 = 72924
- 41 + 72883 = 72924
- 53 + 72871 = 72924
- 101 + 72823 = 72924
- 107 + 72817 = 72924
Showing the first eight; more decompositions exist.
