Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28472, here are decompositions:
- 43 + 28429 = 28472
- 61 + 28411 = 28472
- 79 + 28393 = 28472
- 163 + 28309 = 28472
- 193 + 28279 = 28472
- 271 + 28201 = 28472
- 349 + 28123 = 28472
- 373 + 28099 = 28472
Showing the first eight; more decompositions exist.
