Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54172, here are decompositions:
- 5 + 54167 = 54172
- 71 + 54101 = 54172
- 89 + 54083 = 54172
- 113 + 54059 = 54172
- 179 + 53993 = 54172
- 233 + 53939 = 54172
- 281 + 53891 = 54172
- 311 + 53861 = 54172
Showing the first eight; more decompositions exist.
