Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45142, here are decompositions:
- 3 + 45139 = 45142
- 5 + 45137 = 45142
- 11 + 45131 = 45142
- 23 + 45119 = 45142
- 59 + 45083 = 45142
- 89 + 45053 = 45142
- 179 + 44963 = 45142
- 233 + 44909 = 45142
Showing the first eight; more decompositions exist.
