Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30132, here are decompositions:
- 13 + 30119 = 30132
- 19 + 30113 = 30132
- 23 + 30109 = 30132
- 29 + 30103 = 30132
- 41 + 30091 = 30132
- 43 + 30089 = 30132
- 61 + 30071 = 30132
- 73 + 30059 = 30132
Showing the first eight; more decompositions exist.
