Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4862, here are decompositions:
- 31 + 4831 = 4862
- 61 + 4801 = 4862
- 73 + 4789 = 4862
- 79 + 4783 = 4862
- 103 + 4759 = 4862
- 139 + 4723 = 4862
- 199 + 4663 = 4862
- 211 + 4651 = 4862
Showing the first eight; more decompositions exist.
