Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494144, here are decompositions:

47 + 31494097 = 31494144
53 + 31494091 = 31494144
61 + 31494083 = 31494144
103 + 31494041 = 31494144
193 + 31493951 = 31494144
263 + 31493881 = 31494144
293 + 31493851 = 31494144
401 + 31493743 = 31494144

Showing the first eight; more decompositions exist.
