Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43778, here are decompositions:
- 19 + 43759 = 43778
- 61 + 43717 = 43778
- 67 + 43711 = 43778
- 109 + 43669 = 43778
- 127 + 43651 = 43778
- 151 + 43627 = 43778
- 181 + 43597 = 43778
- 199 + 43579 = 43778
Showing the first eight; more decompositions exist.
