Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80472, here are decompositions:
- 23 + 80449 = 80472
- 43 + 80429 = 80472
- 103 + 80369 = 80472
- 109 + 80363 = 80472
- 131 + 80341 = 80472
- 163 + 80309 = 80472
- 193 + 80279 = 80472
- 199 + 80273 = 80472
Showing the first eight; more decompositions exist.
