Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74778, here are decompositions:
- 7 + 74771 = 74778
- 17 + 74761 = 74778
- 19 + 74759 = 74778
- 31 + 74747 = 74778
- 47 + 74731 = 74778
- 59 + 74719 = 74778
- 61 + 74717 = 74778
- 71 + 74707 = 74778
Showing the first eight; more decompositions exist.
