Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624172, here are decompositions:
- 13 + 8624159 = 8624172
- 19 + 8624153 = 8624172
- 31 + 8624141 = 8624172
- 41 + 8624131 = 8624172
- 43 + 8624129 = 8624172
- 61 + 8624111 = 8624172
- 71 + 8624101 = 8624172
- 113 + 8624059 = 8624172
Showing the first eight; more decompositions exist.
