Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87436, here are decompositions:
- 3 + 87433 = 87436
- 29 + 87407 = 87436
- 53 + 87383 = 87436
- 113 + 87323 = 87436
- 137 + 87299 = 87436
- 179 + 87257 = 87436
- 257 + 87179 = 87436
- 317 + 87119 = 87436
Showing the first eight; more decompositions exist.
