Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148288, here are decompositions:
- 59 + 148229 = 148288
- 89 + 148199 = 148288
- 131 + 148157 = 148288
- 137 + 148151 = 148288
- 149 + 148139 = 148288
- 197 + 148091 = 148288
- 227 + 148061 = 148288
- 311 + 147977 = 148288
Showing the first eight; more decompositions exist.
