Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54138, here are decompositions:
- 5 + 54133 = 54138
- 17 + 54121 = 54138
- 37 + 54101 = 54138
- 47 + 54091 = 54138
- 79 + 54059 = 54138
- 89 + 54049 = 54138
- 101 + 54037 = 54138
- 127 + 54011 = 54138
Showing the first eight; more decompositions exist.
