Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524802, here are decompositions:

5 + 31524797 = 31524802
11 + 31524791 = 31524802
233 + 31524569 = 31524802
269 + 31524533 = 31524802
293 + 31524509 = 31524802
383 + 31524419 = 31524802
509 + 31524293 = 31524802
641 + 31524161 = 31524802

Showing the first eight; more decompositions exist.
