Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535742, here are decompositions:
- 61 + 31535681 = 31535742
- 71 + 31535671 = 31535742
- 103 + 31535639 = 31535742
- 109 + 31535633 = 31535742
- 149 + 31535593 = 31535742
- 151 + 31535591 = 31535742
- 191 + 31535551 = 31535742
- 193 + 31535549 = 31535742
Showing the first eight; more decompositions exist.
