Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45180, here are decompositions:
- 19 + 45161 = 45180
- 41 + 45139 = 45180
- 43 + 45137 = 45180
- 53 + 45127 = 45180
- 59 + 45121 = 45180
- 61 + 45119 = 45180
- 97 + 45083 = 45180
- 103 + 45077 = 45180
Showing the first eight; more decompositions exist.
