Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524626, here are decompositions:

19 + 31524607 = 31524626
103 + 31524523 = 31524626
109 + 31524517 = 31524626
127 + 31524499 = 31524626
157 + 31524469 = 31524626
223 + 31524403 = 31524626
283 + 31524343 = 31524626
349 + 31524277 = 31524626

Showing the first eight; more decompositions exist.
