Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80542, here are decompositions:
- 5 + 80537 = 80542
- 29 + 80513 = 80542
- 53 + 80489 = 80542
- 71 + 80471 = 80542
- 113 + 80429 = 80542
- 173 + 80369 = 80542
- 179 + 80363 = 80542
- 233 + 80309 = 80542
Showing the first eight; more decompositions exist.
