Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45130, here are decompositions:
- 3 + 45127 = 45130
- 11 + 45119 = 45130
- 47 + 45083 = 45130
- 53 + 45077 = 45130
- 167 + 44963 = 45130
- 191 + 44939 = 45130
- 251 + 44879 = 45130
- 263 + 44867 = 45130
Showing the first eight; more decompositions exist.
