Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155952, here are decompositions:
- 31 + 155921 = 155952
- 59 + 155893 = 155952
- 61 + 155891 = 155952
- 89 + 155863 = 155952
- 101 + 155851 = 155952
- 103 + 155849 = 155952
- 131 + 155821 = 155952
- 151 + 155801 = 155952
Showing the first eight; more decompositions exist.
