Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147688, here are decompositions:
- 17 + 147671 = 147688
- 41 + 147647 = 147688
- 59 + 147629 = 147688
- 71 + 147617 = 147688
- 131 + 147557 = 147688
- 137 + 147551 = 147688
- 239 + 147449 = 147688
- 269 + 147419 = 147688
Showing the first eight; more decompositions exist.
