Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54840, here are decompositions:
- 7 + 54833 = 54840
- 11 + 54829 = 54840
- 41 + 54799 = 54840
- 53 + 54787 = 54840
- 61 + 54779 = 54840
- 67 + 54773 = 54840
- 73 + 54767 = 54840
- 89 + 54751 = 54840
Showing the first eight; more decompositions exist.
