Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87610, here are decompositions:
- 23 + 87587 = 87610
- 53 + 87557 = 87610
- 71 + 87539 = 87610
- 101 + 87509 = 87610
- 137 + 87473 = 87610
- 167 + 87443 = 87610
- 227 + 87383 = 87610
- 251 + 87359 = 87610
Showing the first eight; more decompositions exist.
