Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63870, here are decompositions:
- 7 + 63863 = 63870
- 13 + 63857 = 63870
- 17 + 63853 = 63870
- 29 + 63841 = 63870
- 31 + 63839 = 63870
- 47 + 63823 = 63870
- 61 + 63809 = 63870
- 67 + 63803 = 63870
Showing the first eight; more decompositions exist.
