Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504582, here are decompositions:

89 + 31504493 = 31504582
101 + 31504481 = 31504582
353 + 31504229 = 31504582
449 + 31504133 = 31504582
479 + 31504103 = 31504582
569 + 31504013 = 31504582
653 + 31503929 = 31504582
719 + 31503863 = 31504582

Showing the first eight; more decompositions exist.
