Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497382, here are decompositions:

23 + 31497359 = 31497382
29 + 31497353 = 31497382
41 + 31497341 = 31497382
83 + 31497299 = 31497382
89 + 31497293 = 31497382
131 + 31497251 = 31497382
311 + 31497071 = 31497382
419 + 31496963 = 31497382

Showing the first eight; more decompositions exist.
