Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524182, here are decompositions:

139 + 31524043 = 31524182
229 + 31523953 = 31524182
241 + 31523941 = 31524182
331 + 31523851 = 31524182
379 + 31523803 = 31524182
421 + 31523761 = 31524182
433 + 31523749 = 31524182
523 + 31523659 = 31524182

Showing the first eight; more decompositions exist.
