Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63872, here are decompositions:
- 19 + 63853 = 63872
- 31 + 63841 = 63872
- 73 + 63799 = 63872
- 79 + 63793 = 63872
- 163 + 63709 = 63872
- 181 + 63691 = 63872
- 223 + 63649 = 63872
- 271 + 63601 = 63872
Showing the first eight; more decompositions exist.
