Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30156, here are decompositions:
- 17 + 30139 = 30156
- 19 + 30137 = 30156
- 23 + 30133 = 30156
- 37 + 30119 = 30156
- 43 + 30113 = 30156
- 47 + 30109 = 30156
- 53 + 30103 = 30156
- 59 + 30097 = 30156
Showing the first eight; more decompositions exist.
