Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627472, here are decompositions:
- 5 + 8627467 = 8627472
- 31 + 8627441 = 8627472
- 41 + 8627431 = 8627472
- 43 + 8627429 = 8627472
- 101 + 8627371 = 8627472
- 109 + 8627363 = 8627472
- 131 + 8627341 = 8627472
- 151 + 8627321 = 8627472
Showing the first eight; more decompositions exist.
