Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45438, here are decompositions:
- 5 + 45433 = 45438
- 11 + 45427 = 45438
- 61 + 45377 = 45438
- 97 + 45341 = 45438
- 101 + 45337 = 45438
- 109 + 45329 = 45438
- 131 + 45307 = 45438
- 149 + 45289 = 45438
Showing the first eight; more decompositions exist.
