Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64884, here are decompositions:
- 5 + 64879 = 64884
- 7 + 64877 = 64884
- 13 + 64871 = 64884
- 31 + 64853 = 64884
- 67 + 64817 = 64884
- 73 + 64811 = 64884
- 101 + 64783 = 64884
- 103 + 64781 = 64884
Showing the first eight; more decompositions exist.
