Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155844, here are decompositions:
- 11 + 155833 = 155844
- 23 + 155821 = 155844
- 43 + 155801 = 155844
- 47 + 155797 = 155844
- 61 + 155783 = 155844
- 67 + 155777 = 155844
- 71 + 155773 = 155844
- 97 + 155747 = 155844
Showing the first eight; more decompositions exist.
