Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53518, here are decompositions:
- 11 + 53507 = 53518
- 107 + 53411 = 53518
- 137 + 53381 = 53518
- 191 + 53327 = 53518
- 239 + 53279 = 53518
- 251 + 53267 = 53518
- 317 + 53201 = 53518
- 347 + 53171 = 53518
Showing the first eight; more decompositions exist.
