Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148402, here are decompositions:
- 3 + 148399 = 148402
- 41 + 148361 = 148402
- 71 + 148331 = 148402
- 101 + 148301 = 148402
- 173 + 148229 = 148402
- 251 + 148151 = 148402
- 263 + 148139 = 148402
- 311 + 148091 = 148402
Showing the first eight; more decompositions exist.
