Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535136, here are decompositions:
- 5 + 31535131 = 31535136
- 13 + 31535123 = 31535136
- 23 + 31535113 = 31535136
- 29 + 31535107 = 31535136
- 53 + 31535083 = 31535136
- 79 + 31535057 = 31535136
- 103 + 31535033 = 31535136
- 137 + 31534999 = 31535136
Showing the first eight; more decompositions exist.
