Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492972, here are decompositions:
- 5 + 492967 = 492972
- 61 + 492911 = 492972
- 71 + 492901 = 492972
- 79 + 492893 = 492972
- 89 + 492883 = 492972
- 101 + 492871 = 492972
- 173 + 492799 = 492972
- 191 + 492781 = 492972
Showing the first eight; more decompositions exist.
