Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558004, here are decompositions:
- 7 + 31557997 = 31558004
- 43 + 31557961 = 31558004
- 67 + 31557937 = 31558004
- 73 + 31557931 = 31558004
- 193 + 31557811 = 31558004
- 271 + 31557733 = 31558004
- 307 + 31557697 = 31558004
- 367 + 31557637 = 31558004
Showing the first eight; more decompositions exist.
