Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31844, here are decompositions:
- 73 + 31771 = 31844
- 103 + 31741 = 31844
- 157 + 31687 = 31844
- 181 + 31663 = 31844
- 271 + 31573 = 31844
- 277 + 31567 = 31844
- 313 + 31531 = 31844
- 331 + 31513 = 31844
Showing the first eight; more decompositions exist.
