Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163448, here are decompositions:
- 31 + 163417 = 163448
- 37 + 163411 = 163448
- 97 + 163351 = 163448
- 127 + 163321 = 163448
- 139 + 163309 = 163448
- 199 + 163249 = 163448
- 277 + 163171 = 163448
- 331 + 163117 = 163448
Showing the first eight; more decompositions exist.
