Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158452, here are decompositions:
- 3 + 158449 = 158452
- 23 + 158429 = 158452
- 59 + 158393 = 158452
- 89 + 158363 = 158452
- 101 + 158351 = 158452
- 149 + 158303 = 158452
- 191 + 158261 = 158452
- 251 + 158201 = 158452
Showing the first eight; more decompositions exist.
