Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80440, here are decompositions:
- 11 + 80429 = 80440
- 53 + 80387 = 80440
- 71 + 80369 = 80440
- 131 + 80309 = 80440
- 167 + 80273 = 80440
- 233 + 80207 = 80440
- 263 + 80177 = 80440
- 293 + 80147 = 80440
Showing the first eight; more decompositions exist.
