Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047628, here are decompositions:
- 41 + 1047587 = 1047628
- 89 + 1047539 = 1047628
- 137 + 1047491 = 1047628
- 149 + 1047479 = 1047628
- 311 + 1047317 = 1047628
- 317 + 1047311 = 1047628
- 347 + 1047281 = 1047628
- 389 + 1047239 = 1047628
Showing the first eight; more decompositions exist.
