Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738860, here are decompositions:
- 17 + 8738843 = 8738860
- 23 + 8738837 = 8738860
- 47 + 8738813 = 8738860
- 59 + 8738801 = 8738860
- 101 + 8738759 = 8738860
- 131 + 8738729 = 8738860
- 149 + 8738711 = 8738860
- 269 + 8738591 = 8738860
Showing the first eight; more decompositions exist.
