Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500544, here are decompositions:

41 + 31500503 = 31500544
137 + 31500407 = 31500544
167 + 31500377 = 31500544
191 + 31500353 = 31500544
263 + 31500281 = 31500544
281 + 31500263 = 31500544
347 + 31500197 = 31500544
431 + 31500113 = 31500544

Showing the first eight; more decompositions exist.
