Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55280, here are decompositions:
- 31 + 55249 = 55280
- 37 + 55243 = 55280
- 61 + 55219 = 55280
- 67 + 55213 = 55280
- 73 + 55207 = 55280
- 79 + 55201 = 55280
- 109 + 55171 = 55280
- 163 + 55117 = 55280
Showing the first eight; more decompositions exist.
