Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45240, here are decompositions:
- 7 + 45233 = 45240
- 43 + 45197 = 45240
- 59 + 45181 = 45240
- 61 + 45179 = 45240
- 79 + 45161 = 45240
- 101 + 45139 = 45240
- 103 + 45137 = 45240
- 109 + 45131 = 45240
Showing the first eight; more decompositions exist.
