Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472292, here are decompositions:

31 + 31472261 = 31472292
53 + 31472239 = 31472292
83 + 31472209 = 31472292
101 + 31472191 = 31472292
109 + 31472183 = 31472292
113 + 31472179 = 31472292
139 + 31472153 = 31472292
149 + 31472143 = 31472292

Showing the first eight; more decompositions exist.
