Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149272, here are decompositions:
- 3 + 149269 = 149272
- 23 + 149249 = 149272
- 59 + 149213 = 149272
- 89 + 149183 = 149272
- 113 + 149159 = 149272
- 173 + 149099 = 149272
- 239 + 149033 = 149272
- 251 + 149021 = 149272
Showing the first eight; more decompositions exist.
