Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64250, here are decompositions:
- 13 + 64237 = 64250
- 19 + 64231 = 64250
- 61 + 64189 = 64250
- 79 + 64171 = 64250
- 97 + 64153 = 64250
- 127 + 64123 = 64250
- 337 + 63913 = 64250
- 349 + 63901 = 64250
Showing the first eight; more decompositions exist.
