Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53842, here are decompositions:
- 11 + 53831 = 53842
- 23 + 53819 = 53842
- 29 + 53813 = 53842
- 59 + 53783 = 53842
- 83 + 53759 = 53842
- 149 + 53693 = 53842
- 233 + 53609 = 53842
- 251 + 53591 = 53842
Showing the first eight; more decompositions exist.
