Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30750, here are decompositions:
- 23 + 30727 = 30750
- 37 + 30713 = 30750
- 43 + 30707 = 30750
- 47 + 30703 = 30750
- 53 + 30697 = 30750
- 61 + 30689 = 30750
- 73 + 30677 = 30750
- 79 + 30671 = 30750
Showing the first eight; more decompositions exist.
