Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544048, here are decompositions:

7 + 31544041 = 31544048
37 + 31544011 = 31544048
61 + 31543987 = 31544048
271 + 31543777 = 31544048
337 + 31543711 = 31544048
379 + 31543669 = 31544048
619 + 31543429 = 31544048
829 + 31543219 = 31544048

Showing the first eight; more decompositions exist.
