Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744990, here are decompositions:
- 61 + 8744929 = 8744990
- 73 + 8744917 = 8744990
- 103 + 8744887 = 8744990
- 157 + 8744833 = 8744990
- 283 + 8744707 = 8744990
- 307 + 8744683 = 8744990
- 379 + 8744611 = 8744990
- 433 + 8744557 = 8744990
Showing the first eight; more decompositions exist.
