Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504552, here are decompositions:

5 + 31504547 = 31504552
59 + 31504493 = 31504552
71 + 31504481 = 31504552
113 + 31504439 = 31504552
179 + 31504373 = 31504552
419 + 31504133 = 31504552
449 + 31504103 = 31504552
641 + 31503911 = 31504552

Showing the first eight; more decompositions exist.
