Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 52440, here are decompositions:
- 7 + 52433 = 52440
- 53 + 52387 = 52440
- 61 + 52379 = 52440
- 71 + 52369 = 52440
- 79 + 52361 = 52440
- 127 + 52313 = 52440
- 139 + 52301 = 52440
- 149 + 52291 = 52440
Showing the first eight; more decompositions exist.
