Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54040, here are decompositions:
- 3 + 54037 = 54040
- 29 + 54011 = 54040
- 47 + 53993 = 54040
- 53 + 53987 = 54040
- 89 + 53951 = 54040
- 101 + 53939 = 54040
- 113 + 53927 = 54040
- 149 + 53891 = 54040
Showing the first eight; more decompositions exist.
