Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42030, here are decompositions:
- 7 + 42023 = 42030
- 11 + 42019 = 42030
- 13 + 42017 = 42030
- 17 + 42013 = 42030
- 31 + 41999 = 42030
- 47 + 41983 = 42030
- 61 + 41969 = 42030
- 71 + 41959 = 42030
Showing the first eight; more decompositions exist.
