Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129482, here are decompositions:
- 13 + 129469 = 129482
- 43 + 129439 = 129482
- 79 + 129403 = 129482
- 103 + 129379 = 129482
- 193 + 129289 = 129482
- 313 + 129169 = 129482
- 421 + 129061 = 129482
- 433 + 129049 = 129482
Showing the first eight; more decompositions exist.
