Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87574, here are decompositions:
- 17 + 87557 = 87574
- 83 + 87491 = 87574
- 101 + 87473 = 87574
- 131 + 87443 = 87574
- 167 + 87407 = 87574
- 191 + 87383 = 87574
- 251 + 87323 = 87574
- 257 + 87317 = 87574
Showing the first eight; more decompositions exist.
