Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472182, here are decompositions:

3 + 31472179 = 31472182
23 + 31472159 = 31472182
29 + 31472153 = 31472182
59 + 31472123 = 31472182
113 + 31472069 = 31472182
179 + 31472003 = 31472182
191 + 31471991 = 31472182
281 + 31471901 = 31472182

Showing the first eight; more decompositions exist.
