Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039742, here are decompositions:
- 61 + 1039681 = 1039742
- 139 + 1039603 = 1039742
- 199 + 1039543 = 1039742
- 229 + 1039513 = 1039742
- 313 + 1039429 = 1039742
- 421 + 1039321 = 1039742
- 463 + 1039279 = 1039742
- 631 + 1039111 = 1039742
Showing the first eight; more decompositions exist.
