Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2738, here are decompositions:
- 7 + 2731 = 2738
- 19 + 2719 = 2738
- 31 + 2707 = 2738
- 61 + 2677 = 2738
- 67 + 2671 = 2738
- 79 + 2659 = 2738
- 181 + 2557 = 2738
- 199 + 2539 = 2738
Showing the first eight; more decompositions exist.
