Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543444, here are decompositions:

47 + 31543397 = 31543444
83 + 31543361 = 31543444
113 + 31543331 = 31543444
227 + 31543217 = 31543444
263 + 31543181 = 31543444
281 + 31543163 = 31543444
311 + 31543133 = 31543444
503 + 31542941 = 31543444

Showing the first eight; more decompositions exist.
