Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28802, here are decompositions:
- 13 + 28789 = 28802
- 31 + 28771 = 28802
- 43 + 28759 = 28802
- 73 + 28729 = 28802
- 79 + 28723 = 28802
- 139 + 28663 = 28802
- 181 + 28621 = 28802
- 199 + 28603 = 28802
Showing the first eight; more decompositions exist.
