Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55248, here are decompositions:
- 5 + 55243 = 55248
- 19 + 55229 = 55248
- 29 + 55219 = 55248
- 31 + 55217 = 55248
- 41 + 55207 = 55248
- 47 + 55201 = 55248
- 101 + 55147 = 55248
- 131 + 55117 = 55248
Showing the first eight; more decompositions exist.
