Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149250, here are decompositions:
- 11 + 149239 = 149250
- 37 + 149213 = 149250
- 53 + 149197 = 149250
- 67 + 149183 = 149250
- 89 + 149161 = 149250
- 97 + 149153 = 149250
- 107 + 149143 = 149250
- 131 + 149119 = 149250
Showing the first eight; more decompositions exist.
