Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55170, here are decompositions:
- 7 + 55163 = 55170
- 23 + 55147 = 55170
- 43 + 55127 = 55170
- 53 + 55117 = 55170
- 61 + 55109 = 55170
- 67 + 55103 = 55170
- 97 + 55073 = 55170
- 109 + 55061 = 55170
Showing the first eight; more decompositions exist.
