Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560746, here are decompositions:
- 37 + 31560709 = 31560746
- 43 + 31560703 = 31560746
- 67 + 31560679 = 31560746
- 73 + 31560673 = 31560746
- 157 + 31560589 = 31560746
- 163 + 31560583 = 31560746
- 223 + 31560523 = 31560746
- 277 + 31560469 = 31560746
Showing the first eight; more decompositions exist.
