Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472192, here are decompositions:

13 + 31472179 = 31472192
43 + 31472149 = 31472192
61 + 31472131 = 31472192
139 + 31472053 = 31472192
151 + 31472041 = 31472192
163 + 31472029 = 31472192
181 + 31472011 = 31472192
571 + 31471621 = 31472192

Showing the first eight; more decompositions exist.
