Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473052, here are decompositions:

11 + 31473041 = 31473052
89 + 31472963 = 31473052
173 + 31472879 = 31473052
239 + 31472813 = 31473052
353 + 31472699 = 31473052
383 + 31472669 = 31473052
389 + 31472663 = 31473052
419 + 31472633 = 31473052

Showing the first eight; more decompositions exist.
