Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80478, here are decompositions:
- 5 + 80473 = 80478
- 7 + 80471 = 80478
- 29 + 80449 = 80478
- 31 + 80447 = 80478
- 71 + 80407 = 80478
- 109 + 80369 = 80478
- 131 + 80347 = 80478
- 137 + 80341 = 80478
Showing the first eight; more decompositions exist.
