Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504658, here are decompositions:

7 + 31504651 = 31504658
67 + 31504591 = 31504658
271 + 31504387 = 31504658
307 + 31504351 = 31504658
331 + 31504327 = 31504658
439 + 31504219 = 31504658
457 + 31504201 = 31504658
571 + 31504087 = 31504658

Showing the first eight; more decompositions exist.
