Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504938, here are decompositions:

29 + 31504909 = 31504938
137 + 31504801 = 31504938
139 + 31504799 = 31504938
191 + 31504747 = 31504938
271 + 31504667 = 31504938
277 + 31504661 = 31504938
331 + 31504607 = 31504938
347 + 31504591 = 31504938

Showing the first eight; more decompositions exist.
