Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031742, here are decompositions:
- 11 + 1031731 = 1031742
- 13 + 1031729 = 1031742
- 73 + 1031669 = 1031742
- 109 + 1031633 = 1031742
- 113 + 1031629 = 1031742
- 149 + 1031593 = 1031742
- 181 + 1031561 = 1031742
- 193 + 1031549 = 1031742
Showing the first eight; more decompositions exist.
