Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64572, here are decompositions:
- 5 + 64567 = 64572
- 19 + 64553 = 64572
- 59 + 64513 = 64572
- 73 + 64499 = 64572
- 83 + 64489 = 64572
- 89 + 64483 = 64572
- 139 + 64433 = 64572
- 173 + 64399 = 64572
Showing the first eight; more decompositions exist.
