Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504852, here are decompositions:

53 + 31504799 = 31504852
149 + 31504703 = 31504852
191 + 31504661 = 31504852
233 + 31504619 = 31504852
359 + 31504493 = 31504852
479 + 31504373 = 31504852
719 + 31504133 = 31504852
839 + 31504013 = 31504852

Showing the first eight; more decompositions exist.
