Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72378, here are decompositions:
- 11 + 72367 = 72378
- 37 + 72341 = 72378
- 41 + 72337 = 72378
- 71 + 72307 = 72378
- 101 + 72277 = 72378
- 107 + 72271 = 72378
- 109 + 72269 = 72378
- 127 + 72251 = 72378
Showing the first eight; more decompositions exist.
