Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503532, here are decompositions:

3 + 31503529 = 31503532
23 + 31503509 = 31503532
89 + 31503443 = 31503532
191 + 31503341 = 31503532
353 + 31503179 = 31503532
479 + 31503053 = 31503532
569 + 31502963 = 31503532
971 + 31502561 = 31503532

Showing the first eight; more decompositions exist.
