Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157240, here are decompositions:
- 11 + 157229 = 157240
- 23 + 157217 = 157240
- 29 + 157211 = 157240
- 59 + 157181 = 157240
- 107 + 157133 = 157240
- 113 + 157127 = 157240
- 131 + 157109 = 157240
- 137 + 157103 = 157240
Showing the first eight; more decompositions exist.
