Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64830, here are decompositions:
- 13 + 64817 = 64830
- 19 + 64811 = 64830
- 37 + 64793 = 64830
- 47 + 64783 = 64830
- 67 + 64763 = 64830
- 83 + 64747 = 64830
- 113 + 64717 = 64830
- 137 + 64693 = 64830
Showing the first eight; more decompositions exist.
