Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102748, here are decompositions:
- 47 + 102701 = 102748
- 71 + 102677 = 102748
- 101 + 102647 = 102748
- 137 + 102611 = 102748
- 197 + 102551 = 102748
- 251 + 102497 = 102748
- 311 + 102437 = 102748
- 389 + 102359 = 102748
Showing the first eight; more decompositions exist.
