Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55240, here are decompositions:
- 11 + 55229 = 55240
- 23 + 55217 = 55240
- 113 + 55127 = 55240
- 131 + 55109 = 55240
- 137 + 55103 = 55240
- 167 + 55073 = 55240
- 179 + 55061 = 55240
- 191 + 55049 = 55240
Showing the first eight; more decompositions exist.
