Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53440, here are decompositions:
- 3 + 53437 = 53440
- 29 + 53411 = 53440
- 59 + 53381 = 53440
- 113 + 53327 = 53440
- 131 + 53309 = 53440
- 173 + 53267 = 53440
- 239 + 53201 = 53440
- 251 + 53189 = 53440
Showing the first eight; more decompositions exist.
