Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472244, here are decompositions:

5 + 31472239 = 31472244
43 + 31472201 = 31472244
53 + 31472191 = 31472244
61 + 31472183 = 31472244
101 + 31472143 = 31472244
113 + 31472131 = 31472244
137 + 31472107 = 31472244
191 + 31472053 = 31472244

Showing the first eight; more decompositions exist.
