Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502824, here are decompositions:

47 + 31502777 = 31502824
137 + 31502687 = 31502824
263 + 31502561 = 31502824
383 + 31502441 = 31502824
461 + 31502363 = 31502824
491 + 31502333 = 31502824
641 + 31502183 = 31502824
677 + 31502147 = 31502824

Showing the first eight; more decompositions exist.
