Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542054, here are decompositions:

17 + 31542037 = 31542054
23 + 31542031 = 31542054
31 + 31542023 = 31542054
41 + 31542013 = 31542054
43 + 31542011 = 31542054
53 + 31542001 = 31542054
73 + 31541981 = 31542054
83 + 31541971 = 31542054

Showing the first eight; more decompositions exist.
