Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462946, here are decompositions:

13 + 31462933 = 31462946
37 + 31462909 = 31462946
139 + 31462807 = 31462946
199 + 31462747 = 31462946
223 + 31462723 = 31462946
337 + 31462609 = 31462946
367 + 31462579 = 31462946
373 + 31462573 = 31462946

Showing the first eight; more decompositions exist.
