Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80436, here are decompositions:
- 7 + 80429 = 80436
- 29 + 80407 = 80436
- 67 + 80369 = 80436
- 73 + 80363 = 80436
- 89 + 80347 = 80436
- 107 + 80329 = 80436
- 127 + 80309 = 80436
- 149 + 80287 = 80436
Showing the first eight; more decompositions exist.
