Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147844, here are decompositions:
- 17 + 147827 = 147844
- 71 + 147773 = 147844
- 83 + 147761 = 147844
- 101 + 147743 = 147844
- 173 + 147671 = 147844
- 197 + 147647 = 147844
- 227 + 147617 = 147844
- 293 + 147551 = 147844
Showing the first eight; more decompositions exist.
