Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472184, here are decompositions:

5 + 31472179 = 31472184
17 + 31472167 = 31472184
31 + 31472153 = 31472184
41 + 31472143 = 31472184
53 + 31472131 = 31472184
61 + 31472123 = 31472184
131 + 31472053 = 31472184
173 + 31472011 = 31472184

Showing the first eight; more decompositions exist.
