Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524478, here are decompositions:

59 + 31524419 = 31524478
281 + 31524197 = 31524478
311 + 31524167 = 31524478
317 + 31524161 = 31524478
431 + 31524047 = 31524478
467 + 31524011 = 31524478
677 + 31523801 = 31524478
809 + 31523669 = 31524478

Showing the first eight; more decompositions exist.
