Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504576, here are decompositions:

3 + 31504573 = 31504576
29 + 31504547 = 31504576
83 + 31504493 = 31504576
137 + 31504439 = 31504576
347 + 31504229 = 31504576
443 + 31504133 = 31504576
449 + 31504127 = 31504576
479 + 31504097 = 31504576

Showing the first eight; more decompositions exist.
