Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81348, here are decompositions:
- 5 + 81343 = 81348
- 17 + 81331 = 81348
- 41 + 81307 = 81348
- 67 + 81281 = 81348
- 109 + 81239 = 81348
- 149 + 81199 = 81348
- 151 + 81197 = 81348
- 167 + 81181 = 81348
Showing the first eight; more decompositions exist.
