Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55250, here are decompositions:
- 7 + 55243 = 55250
- 31 + 55219 = 55250
- 37 + 55213 = 55250
- 43 + 55207 = 55250
- 79 + 55171 = 55250
- 103 + 55147 = 55250
- 193 + 55057 = 55250
- 199 + 55051 = 55250
Showing the first eight; more decompositions exist.
