Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503058, here are decompositions:

5 + 31503053 = 31503058
131 + 31502927 = 31503058
281 + 31502777 = 31503058
359 + 31502699 = 31503058
569 + 31502489 = 31503058
599 + 31502459 = 31503058
617 + 31502441 = 31503058
911 + 31502147 = 31503058

Showing the first eight; more decompositions exist.
