Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562946, here are decompositions:

29 + 31562917 = 31562946
97 + 31562849 = 31562946
167 + 31562779 = 31562946
179 + 31562767 = 31562946
263 + 31562683 = 31562946
269 + 31562677 = 31562946
353 + 31562593 = 31562946
379 + 31562567 = 31562946

Showing the first eight; more decompositions exist.
