Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29820, here are decompositions:
- 17 + 29803 = 29820
- 31 + 29789 = 29820
- 59 + 29761 = 29820
- 61 + 29759 = 29820
- 67 + 29753 = 29820
- 79 + 29741 = 29820
- 97 + 29723 = 29820
- 103 + 29717 = 29820
Showing the first eight; more decompositions exist.
