Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47642, here are decompositions:
- 3 + 47639 = 47642
- 13 + 47629 = 47642
- 19 + 47623 = 47642
- 43 + 47599 = 47642
- 61 + 47581 = 47642
- 73 + 47569 = 47642
- 79 + 47563 = 47642
- 109 + 47533 = 47642
Showing the first eight; more decompositions exist.
