Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80438, here are decompositions:
- 31 + 80407 = 80438
- 97 + 80341 = 80438
- 109 + 80329 = 80438
- 151 + 80287 = 80438
- 199 + 80239 = 80438
- 229 + 80209 = 80438
- 271 + 80167 = 80438
- 331 + 80107 = 80438
Showing the first eight; more decompositions exist.
