Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64100, here are decompositions:
- 19 + 64081 = 64100
- 37 + 64063 = 64100
- 67 + 64033 = 64100
- 103 + 63997 = 64100
- 151 + 63949 = 64100
- 193 + 63907 = 64100
- 199 + 63901 = 64100
- 277 + 63823 = 64100
Showing the first eight; more decompositions exist.
