Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51486, here are decompositions:
- 5 + 51481 = 51486
- 7 + 51479 = 51486
- 13 + 51473 = 51486
- 37 + 51449 = 51486
- 47 + 51439 = 51486
- 59 + 51427 = 51486
- 67 + 51419 = 51486
- 73 + 51413 = 51486
Showing the first eight; more decompositions exist.
