Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129474, here are decompositions:
- 5 + 129469 = 129474
- 13 + 129461 = 129474
- 17 + 129457 = 129474
- 31 + 129443 = 129474
- 71 + 129403 = 129474
- 73 + 129401 = 129474
- 113 + 129361 = 129474
- 127 + 129347 = 129474
Showing the first eight; more decompositions exist.
