Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78544, here are decompositions:
- 3 + 78541 = 78544
- 5 + 78539 = 78544
- 47 + 78497 = 78544
- 107 + 78437 = 78544
- 197 + 78347 = 78544
- 227 + 78317 = 78544
- 233 + 78311 = 78544
- 311 + 78233 = 78544
Showing the first eight; more decompositions exist.
