Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87486, here are decompositions:
- 5 + 87481 = 87486
- 13 + 87473 = 87486
- 43 + 87443 = 87486
- 53 + 87433 = 87486
- 59 + 87427 = 87486
- 79 + 87407 = 87486
- 83 + 87403 = 87486
- 103 + 87383 = 87486
Showing the first eight; more decompositions exist.
