Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494060, here are decompositions:

7 + 31494053 = 31494060
19 + 31494041 = 31494060
61 + 31493999 = 31494060
71 + 31493989 = 31494060
109 + 31493951 = 31494060
151 + 31493909 = 31494060
179 + 31493881 = 31494060
239 + 31493821 = 31494060

Showing the first eight; more decompositions exist.
