Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53040, here are decompositions:
- 23 + 53017 = 53040
- 37 + 53003 = 53040
- 41 + 52999 = 53040
- 59 + 52981 = 53040
- 67 + 52973 = 53040
- 73 + 52967 = 53040
- 83 + 52957 = 53040
- 89 + 52951 = 53040
Showing the first eight; more decompositions exist.
