Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504312, here are decompositions:

83 + 31504229 = 31504312
179 + 31504133 = 31504312
383 + 31503929 = 31504312
401 + 31503911 = 31504312
449 + 31503863 = 31504312
503 + 31503809 = 31504312
563 + 31503749 = 31504312
599 + 31503713 = 31504312

Showing the first eight; more decompositions exist.
