Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476804, here are decompositions:

5 + 31476799 = 31476804
61 + 31476743 = 31476804
71 + 31476733 = 31476804
101 + 31476703 = 31476804
113 + 31476691 = 31476804
173 + 31476631 = 31476804
181 + 31476623 = 31476804
193 + 31476611 = 31476804

Showing the first eight; more decompositions exist.
