Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5186, here are decompositions:
- 7 + 5179 = 5186
- 19 + 5167 = 5186
- 67 + 5119 = 5186
- 73 + 5113 = 5186
- 79 + 5107 = 5186
- 109 + 5077 = 5186
- 127 + 5059 = 5186
- 163 + 5023 = 5186
Showing the first eight; more decompositions exist.
