Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45178, here are decompositions:
- 17 + 45161 = 45178
- 41 + 45137 = 45178
- 47 + 45131 = 45178
- 59 + 45119 = 45178
- 101 + 45077 = 45178
- 191 + 44987 = 45178
- 239 + 44939 = 45178
- 251 + 44927 = 45178
Showing the first eight; more decompositions exist.
