Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 141778, here are decompositions:
- 5 + 141773 = 141778
- 11 + 141767 = 141778
- 17 + 141761 = 141778
- 47 + 141731 = 141778
- 59 + 141719 = 141778
- 71 + 141707 = 141778
- 89 + 141689 = 141778
- 101 + 141677 = 141778
Showing the first eight; more decompositions exist.
