Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87190, here are decompositions:
- 3 + 87187 = 87190
- 11 + 87179 = 87190
- 41 + 87149 = 87190
- 71 + 87119 = 87190
- 83 + 87107 = 87190
- 107 + 87083 = 87190
- 149 + 87041 = 87190
- 179 + 87011 = 87190
Showing the first eight; more decompositions exist.
