Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45442, here are decompositions:
- 3 + 45439 = 45442
- 29 + 45413 = 45442
- 53 + 45389 = 45442
- 101 + 45341 = 45442
- 113 + 45329 = 45442
- 149 + 45293 = 45442
- 179 + 45263 = 45442
- 251 + 45191 = 45442
Showing the first eight; more decompositions exist.
