Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87236, here are decompositions:
- 13 + 87223 = 87236
- 103 + 87133 = 87236
- 199 + 87037 = 87236
- 223 + 87013 = 87236
- 277 + 86959 = 87236
- 307 + 86929 = 87236
- 313 + 86923 = 87236
- 367 + 86869 = 87236
Showing the first eight; more decompositions exist.
