Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64824, here are decompositions:
- 7 + 64817 = 64824
- 13 + 64811 = 64824
- 31 + 64793 = 64824
- 41 + 64783 = 64824
- 43 + 64781 = 64824
- 61 + 64763 = 64824
- 107 + 64717 = 64824
- 131 + 64693 = 64824
Showing the first eight; more decompositions exist.
