Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149228, here are decompositions:
- 31 + 149197 = 149228
- 67 + 149161 = 149228
- 109 + 149119 = 149228
- 127 + 149101 = 149228
- 151 + 149077 = 149228
- 271 + 148957 = 149228
- 307 + 148921 = 149228
- 337 + 148891 = 149228
Showing the first eight; more decompositions exist.
