Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10438, here are decompositions:
- 5 + 10433 = 10438
- 11 + 10427 = 10438
- 47 + 10391 = 10438
- 101 + 10337 = 10438
- 107 + 10331 = 10438
- 137 + 10301 = 10438
- 149 + 10289 = 10438
- 167 + 10271 = 10438
Showing the first eight; more decompositions exist.
