Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472082, here are decompositions:

13 + 31472069 = 31472082
29 + 31472053 = 31472082
41 + 31472041 = 31472082
53 + 31472029 = 31472082
71 + 31472011 = 31472082
79 + 31472003 = 31472082
149 + 31471933 = 31472082
181 + 31471901 = 31472082

Showing the first eight; more decompositions exist.
