Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64920, here are decompositions:
- 19 + 64901 = 64920
- 29 + 64891 = 64920
- 41 + 64879 = 64920
- 43 + 64877 = 64920
- 67 + 64853 = 64920
- 71 + 64849 = 64920
- 103 + 64817 = 64920
- 109 + 64811 = 64920
Showing the first eight; more decompositions exist.
