Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472202, here are decompositions:

11 + 31472191 = 31472202
19 + 31472183 = 31472202
23 + 31472179 = 31472202
43 + 31472159 = 31472202
53 + 31472149 = 31472202
59 + 31472143 = 31472202
71 + 31472131 = 31472202
79 + 31472123 = 31472202

Showing the first eight; more decompositions exist.
