Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742216, here are decompositions:
- 19 + 8742197 = 8742216
- 23 + 8742193 = 8742216
- 29 + 8742187 = 8742216
- 47 + 8742169 = 8742216
- 59 + 8742157 = 8742216
- 83 + 8742133 = 8742216
- 113 + 8742103 = 8742216
- 139 + 8742077 = 8742216
Showing the first eight; more decompositions exist.
