Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45520, here are decompositions:
- 17 + 45503 = 45520
- 23 + 45497 = 45520
- 29 + 45491 = 45520
- 107 + 45413 = 45520
- 131 + 45389 = 45520
- 179 + 45341 = 45520
- 191 + 45329 = 45520
- 227 + 45293 = 45520
Showing the first eight; more decompositions exist.
