Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2774, here are decompositions:
- 7 + 2767 = 2774
- 43 + 2731 = 2774
- 61 + 2713 = 2774
- 67 + 2707 = 2774
- 97 + 2677 = 2774
- 103 + 2671 = 2774
- 127 + 2647 = 2774
- 157 + 2617 = 2774
Showing the first eight; more decompositions exist.
