Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527792, here are decompositions:
- 5 + 31527787 = 31527792
- 11 + 31527781 = 31527792
- 83 + 31527709 = 31527792
- 89 + 31527703 = 31527792
- 103 + 31527689 = 31527792
- 223 + 31527569 = 31527792
- 251 + 31527541 = 31527792
- 269 + 31527523 = 31527792
Showing the first eight; more decompositions exist.
