Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78572, here are decompositions:
- 3 + 78569 = 78572
- 19 + 78553 = 78572
- 31 + 78541 = 78572
- 61 + 78511 = 78572
- 271 + 78301 = 78572
- 313 + 78259 = 78572
- 331 + 78241 = 78572
- 379 + 78193 = 78572
Showing the first eight; more decompositions exist.
