Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972990, here are decompositions:
- 13 + 972977 = 972990
- 23 + 972967 = 972990
- 47 + 972943 = 972990
- 89 + 972901 = 972990
- 103 + 972887 = 972990
- 157 + 972833 = 972990
- 163 + 972827 = 972990
- 167 + 972823 = 972990
Showing the first eight; more decompositions exist.
