Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562804, here are decompositions:

3 + 31562801 = 31562804
37 + 31562767 = 31562804
67 + 31562737 = 31562804
127 + 31562677 = 31562804
181 + 31562623 = 31562804
193 + 31562611 = 31562804
211 + 31562593 = 31562804
337 + 31562467 = 31562804

Showing the first eight; more decompositions exist.
