Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503244, here are decompositions:

41 + 31503203 = 31503244
137 + 31503107 = 31503244
191 + 31503053 = 31503244
251 + 31502993 = 31503244
281 + 31502963 = 31503244
317 + 31502927 = 31503244
347 + 31502897 = 31503244
467 + 31502777 = 31503244

Showing the first eight; more decompositions exist.
