Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55488, here are decompositions:
- 19 + 55469 = 55488
- 31 + 55457 = 55488
- 47 + 55441 = 55488
- 89 + 55399 = 55488
- 107 + 55381 = 55488
- 137 + 55351 = 55488
- 149 + 55339 = 55488
- 151 + 55337 = 55488
Showing the first eight; more decompositions exist.
