Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157478, here are decompositions:
- 67 + 157411 = 157478
- 127 + 157351 = 157478
- 151 + 157327 = 157478
- 157 + 157321 = 157478
- 199 + 157279 = 157478
- 271 + 157207 = 157478
- 337 + 157141 = 157478
- 397 + 157081 = 157478
Showing the first eight; more decompositions exist.
