Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87480, here are decompositions:
- 7 + 87473 = 87480
- 37 + 87443 = 87480
- 47 + 87433 = 87480
- 53 + 87427 = 87480
- 59 + 87421 = 87480
- 73 + 87407 = 87480
- 97 + 87383 = 87480
- 157 + 87323 = 87480
Showing the first eight; more decompositions exist.
