Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87544, here are decompositions:
- 3 + 87541 = 87544
- 5 + 87539 = 87544
- 53 + 87491 = 87544
- 71 + 87473 = 87544
- 101 + 87443 = 87544
- 137 + 87407 = 87544
- 227 + 87317 = 87544
- 251 + 87293 = 87544
Showing the first eight; more decompositions exist.
