Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5240, here are decompositions:
- 3 + 5237 = 5240
- 7 + 5233 = 5240
- 13 + 5227 = 5240
- 31 + 5209 = 5240
- 43 + 5197 = 5240
- 61 + 5179 = 5240
- 73 + 5167 = 5240
- 127 + 5113 = 5240
Showing the first eight; more decompositions exist.
