Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747622, here are decompositions:
- 5 + 8747617 = 8747622
- 19 + 8747603 = 8747622
- 43 + 8747579 = 8747622
- 61 + 8747561 = 8747622
- 83 + 8747539 = 8747622
- 109 + 8747513 = 8747622
- 139 + 8747483 = 8747622
- 151 + 8747471 = 8747622
Showing the first eight; more decompositions exist.
