Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87356, here are decompositions:
- 19 + 87337 = 87356
- 43 + 87313 = 87356
- 79 + 87277 = 87356
- 103 + 87253 = 87356
- 223 + 87133 = 87356
- 307 + 87049 = 87356
- 397 + 86959 = 87356
- 433 + 86923 = 87356
Showing the first eight; more decompositions exist.
