Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563084, here are decompositions:
- 11 + 31563073 = 31563084
- 41 + 31563043 = 31563084
- 43 + 31563041 = 31563084
- 53 + 31563031 = 31563084
- 71 + 31563013 = 31563084
- 83 + 31563001 = 31563084
- 97 + 31562987 = 31563084
- 101 + 31562983 = 31563084
Showing the first eight; more decompositions exist.
