Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504958, here are decompositions:

7 + 31504951 = 31504958
139 + 31504819 = 31504958
157 + 31504801 = 31504958
211 + 31504747 = 31504958
307 + 31504651 = 31504958
367 + 31504591 = 31504958
571 + 31504387 = 31504958
601 + 31504357 = 31504958

Showing the first eight; more decompositions exist.
