Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670042, here are decompositions:
- 5 + 8670037 = 8670042
- 11 + 8670031 = 8670042
- 13 + 8670029 = 8670042
- 53 + 8669989 = 8670042
- 61 + 8669981 = 8670042
- 79 + 8669963 = 8670042
- 103 + 8669939 = 8670042
- 113 + 8669929 = 8670042
Showing the first eight; more decompositions exist.
