Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158844, here are decompositions:
- 41 + 158803 = 158844
- 53 + 158791 = 158844
- 67 + 158777 = 158844
- 73 + 158771 = 158844
- 83 + 158761 = 158844
- 97 + 158747 = 158844
- 113 + 158731 = 158844
- 181 + 158663 = 158844
Showing the first eight; more decompositions exist.
