Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102844, here are decompositions:
- 3 + 102841 = 102844
- 47 + 102797 = 102844
- 83 + 102761 = 102844
- 167 + 102677 = 102844
- 191 + 102653 = 102844
- 197 + 102647 = 102844
- 233 + 102611 = 102844
- 251 + 102593 = 102844
Showing the first eight; more decompositions exist.
