Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131292, here are decompositions:
- 41 + 131251 = 131292
- 43 + 131249 = 131292
- 61 + 131231 = 131292
- 71 + 131221 = 131292
- 79 + 131213 = 131292
- 89 + 131203 = 131292
- 149 + 131143 = 131292
- 163 + 131129 = 131292
Showing the first eight; more decompositions exist.
