Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54390, here are decompositions:
- 13 + 54377 = 54390
- 19 + 54371 = 54390
- 23 + 54367 = 54390
- 29 + 54361 = 54390
- 43 + 54347 = 54390
- 59 + 54331 = 54390
- 67 + 54323 = 54390
- 71 + 54319 = 54390
Showing the first eight; more decompositions exist.
