Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504752, here are decompositions:

5 + 31504747 = 31504752
61 + 31504691 = 31504752
101 + 31504651 = 31504752
179 + 31504573 = 31504752
271 + 31504481 = 31504752
313 + 31504439 = 31504752
379 + 31504373 = 31504752
401 + 31504351 = 31504752

Showing the first eight; more decompositions exist.
