Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47646, here are decompositions:
- 7 + 47639 = 47646
- 17 + 47629 = 47646
- 23 + 47623 = 47646
- 37 + 47609 = 47646
- 47 + 47599 = 47646
- 83 + 47563 = 47646
- 103 + 47543 = 47646
- 113 + 47533 = 47646
Showing the first eight; more decompositions exist.
