Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148438, here are decompositions:
- 71 + 148367 = 148438
- 107 + 148331 = 148438
- 137 + 148301 = 148438
- 239 + 148199 = 148438
- 281 + 148157 = 148438
- 347 + 148091 = 148438
- 359 + 148079 = 148438
- 461 + 147977 = 148438
Showing the first eight; more decompositions exist.
