Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64072, here are decompositions:
- 5 + 64067 = 64072
- 53 + 64019 = 64072
- 59 + 64013 = 64072
- 233 + 63839 = 64072
- 263 + 63809 = 64072
- 269 + 63803 = 64072
- 311 + 63761 = 64072
- 353 + 63719 = 64072
Showing the first eight; more decompositions exist.
