Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148448, here are decompositions:
- 19 + 148429 = 148448
- 37 + 148411 = 148448
- 61 + 148387 = 148448
- 67 + 148381 = 148448
- 109 + 148339 = 148448
- 199 + 148249 = 148448
- 241 + 148207 = 148448
- 277 + 148171 = 148448
Showing the first eight; more decompositions exist.
