Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124438, here are decompositions:
- 5 + 124433 = 124438
- 11 + 124427 = 124438
- 71 + 124367 = 124438
- 89 + 124349 = 124438
- 101 + 124337 = 124438
- 137 + 124301 = 124438
- 191 + 124247 = 124438
- 239 + 124199 = 124438
Showing the first eight; more decompositions exist.
