Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56172, here are decompositions:
- 5 + 56167 = 56172
- 23 + 56149 = 56172
- 41 + 56131 = 56172
- 59 + 56113 = 56172
- 71 + 56101 = 56172
- 73 + 56099 = 56172
- 79 + 56093 = 56172
- 131 + 56041 = 56172
Showing the first eight; more decompositions exist.
