Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64212, here are decompositions:
- 23 + 64189 = 64212
- 41 + 64171 = 64212
- 59 + 64153 = 64212
- 61 + 64151 = 64212
- 89 + 64123 = 64212
- 103 + 64109 = 64212
- 131 + 64081 = 64212
- 149 + 64063 = 64212
Showing the first eight; more decompositions exist.
