Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72380, here are decompositions:
- 13 + 72367 = 72380
- 43 + 72337 = 72380
- 67 + 72313 = 72380
- 73 + 72307 = 72380
- 103 + 72277 = 72380
- 109 + 72271 = 72380
- 127 + 72253 = 72380
- 151 + 72229 = 72380
Showing the first eight; more decompositions exist.
