Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687472, here are decompositions:
- 5 + 8687467 = 8687472
- 11 + 8687461 = 8687472
- 19 + 8687453 = 8687472
- 43 + 8687429 = 8687472
- 71 + 8687401 = 8687472
- 89 + 8687383 = 8687472
- 103 + 8687369 = 8687472
- 109 + 8687363 = 8687472
Showing the first eight; more decompositions exist.
