Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147778, here are decompositions:
- 5 + 147773 = 147778
- 17 + 147761 = 147778
- 89 + 147689 = 147778
- 107 + 147671 = 147778
- 131 + 147647 = 147778
- 149 + 147629 = 147778
- 227 + 147551 = 147778
- 359 + 147419 = 147778
Showing the first eight; more decompositions exist.
