Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157144, here are decompositions:
- 3 + 157141 = 157144
- 11 + 157133 = 157144
- 17 + 157127 = 157144
- 41 + 157103 = 157144
- 83 + 157061 = 157144
- 107 + 157037 = 157144
- 131 + 157013 = 157144
- 137 + 157007 = 157144
Showing the first eight; more decompositions exist.
