Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102648, here are decompositions:
- 5 + 102643 = 102648
- 37 + 102611 = 102648
- 41 + 102607 = 102648
- 61 + 102587 = 102648
- 89 + 102559 = 102648
- 97 + 102551 = 102648
- 101 + 102547 = 102648
- 109 + 102539 = 102648
Showing the first eight; more decompositions exist.
