Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87628, here are decompositions:
- 5 + 87623 = 87628
- 41 + 87587 = 87628
- 71 + 87557 = 87628
- 89 + 87539 = 87628
- 137 + 87491 = 87628
- 269 + 87359 = 87628
- 311 + 87317 = 87628
- 347 + 87281 = 87628
Showing the first eight; more decompositions exist.
