Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55400, here are decompositions:
- 19 + 55381 = 55400
- 61 + 55339 = 55400
- 67 + 55333 = 55400
- 109 + 55291 = 55400
- 151 + 55249 = 55400
- 157 + 55243 = 55400
- 181 + 55219 = 55400
- 193 + 55207 = 55400
Showing the first eight; more decompositions exist.
