Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90186, here are decompositions:
- 13 + 90173 = 90186
- 23 + 90163 = 90186
- 37 + 90149 = 90186
- 59 + 90127 = 90186
- 79 + 90107 = 90186
- 97 + 90089 = 90186
- 113 + 90073 = 90186
- 127 + 90059 = 90186
Showing the first eight; more decompositions exist.
