Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72942, here are decompositions:
- 5 + 72937 = 72942
- 11 + 72931 = 72942
- 19 + 72923 = 72942
- 31 + 72911 = 72942
- 41 + 72901 = 72942
- 53 + 72889 = 72942
- 59 + 72883 = 72942
- 71 + 72871 = 72942
Showing the first eight; more decompositions exist.
