Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87090, here are decompositions:
- 7 + 87083 = 87090
- 19 + 87071 = 87090
- 41 + 87049 = 87090
- 53 + 87037 = 87090
- 79 + 87011 = 87090
- 97 + 86993 = 87090
- 109 + 86981 = 87090
- 131 + 86959 = 87090
Showing the first eight; more decompositions exist.
