Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473982, here are decompositions:

5 + 31473977 = 31473982
11 + 31473971 = 31473982
173 + 31473809 = 31473982
383 + 31473599 = 31473982
389 + 31473593 = 31473982
401 + 31473581 = 31473982
503 + 31473479 = 31473982
569 + 31473413 = 31473982

Showing the first eight; more decompositions exist.
