Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473192, here are decompositions:

5 + 31473187 = 31473192
19 + 31473173 = 31473192
29 + 31473163 = 31473192
31 + 31473161 = 31473192
41 + 31473151 = 31473192
83 + 31473109 = 31473192
109 + 31473083 = 31473192
131 + 31473061 = 31473192

Showing the first eight; more decompositions exist.
