Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149226, here are decompositions:
- 13 + 149213 = 149226
- 29 + 149197 = 149226
- 43 + 149183 = 149226
- 53 + 149173 = 149226
- 67 + 149159 = 149226
- 73 + 149153 = 149226
- 83 + 149143 = 149226
- 107 + 149119 = 149226
Showing the first eight; more decompositions exist.
