Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504444, here are decompositions:

5 + 31504439 = 31504444
71 + 31504373 = 31504444
311 + 31504133 = 31504444
317 + 31504127 = 31504444
347 + 31504097 = 31504444
431 + 31504013 = 31504444
467 + 31503977 = 31504444
557 + 31503887 = 31504444

Showing the first eight; more decompositions exist.
