Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148838, here are decompositions:
- 127 + 148711 = 148838
- 199 + 148639 = 148838
- 211 + 148627 = 148838
- 229 + 148609 = 148838
- 307 + 148531 = 148838
- 337 + 148501 = 148838
- 367 + 148471 = 148838
- 409 + 148429 = 148838
Showing the first eight; more decompositions exist.
