Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536780, here are decompositions:
- 7 + 31536773 = 31536780
- 47 + 31536733 = 31536780
- 61 + 31536719 = 31536780
- 73 + 31536707 = 31536780
- 83 + 31536697 = 31536780
- 151 + 31536629 = 31536780
- 167 + 31536613 = 31536780
- 173 + 31536607 = 31536780
Showing the first eight; more decompositions exist.
