Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 62820, here are decompositions:
- 19 + 62801 = 62820
- 29 + 62791 = 62820
- 47 + 62773 = 62820
- 59 + 62761 = 62820
- 67 + 62753 = 62820
- 89 + 62731 = 62820
- 97 + 62723 = 62820
- 137 + 62683 = 62820
Showing the first eight; more decompositions exist.
