Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64236, here are decompositions:
- 5 + 64231 = 64236
- 13 + 64223 = 64236
- 19 + 64217 = 64236
- 47 + 64189 = 64236
- 79 + 64157 = 64236
- 83 + 64153 = 64236
- 113 + 64123 = 64236
- 127 + 64109 = 64236
Showing the first eight; more decompositions exist.
