Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504734, here are decompositions:

31 + 31504703 = 31504734
43 + 31504691 = 31504734
67 + 31504667 = 31504734
73 + 31504661 = 31504734
83 + 31504651 = 31504734
127 + 31504607 = 31504734
167 + 31504567 = 31504734
241 + 31504493 = 31504734

Showing the first eight; more decompositions exist.
