Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131348, here are decompositions:
- 31 + 131317 = 131348
- 37 + 131311 = 131348
- 97 + 131251 = 131348
- 127 + 131221 = 131348
- 199 + 131149 = 131348
- 277 + 131071 = 131348
- 307 + 131041 = 131348
- 337 + 131011 = 131348
Showing the first eight; more decompositions exist.
