Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75142, here are decompositions:
- 59 + 75083 = 75142
- 101 + 75041 = 75142
- 113 + 75029 = 75142
- 131 + 75011 = 75142
- 239 + 74903 = 75142
- 251 + 74891 = 75142
- 269 + 74873 = 75142
- 281 + 74861 = 75142
Showing the first eight; more decompositions exist.
