Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155824, here are decompositions:
- 3 + 155821 = 155824
- 23 + 155801 = 155824
- 41 + 155783 = 155824
- 47 + 155777 = 155824
- 83 + 155741 = 155824
- 101 + 155723 = 155824
- 107 + 155717 = 155824
- 131 + 155693 = 155824
Showing the first eight; more decompositions exist.
