Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149242, here are decompositions:
- 3 + 149239 = 149242
- 29 + 149213 = 149242
- 59 + 149183 = 149242
- 83 + 149159 = 149242
- 89 + 149153 = 149242
- 131 + 149111 = 149242
- 173 + 149069 = 149242
- 251 + 148991 = 149242
Showing the first eight; more decompositions exist.
