Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492942, here are decompositions:
- 31 + 492911 = 492942
- 41 + 492901 = 492942
- 59 + 492883 = 492942
- 71 + 492871 = 492942
- 89 + 492853 = 492942
- 103 + 492839 = 492942
- 173 + 492769 = 492942
- 179 + 492763 = 492942
Showing the first eight; more decompositions exist.
