Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148690, here are decompositions:
- 23 + 148667 = 148690
- 173 + 148517 = 148690
- 233 + 148457 = 148690
- 251 + 148439 = 148690
- 359 + 148331 = 148690
- 389 + 148301 = 148690
- 461 + 148229 = 148690
- 491 + 148199 = 148690
Showing the first eight; more decompositions exist.
