Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72936, here are decompositions:
- 5 + 72931 = 72936
- 13 + 72923 = 72936
- 29 + 72907 = 72936
- 43 + 72893 = 72936
- 47 + 72889 = 72936
- 53 + 72883 = 72936
- 67 + 72869 = 72936
- 113 + 72823 = 72936
Showing the first eight; more decompositions exist.
