Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546830, here are decompositions:

13 + 31546817 = 31546830
17 + 31546813 = 31546830
23 + 31546807 = 31546830
31 + 31546799 = 31546830
41 + 31546789 = 31546830
71 + 31546759 = 31546830
89 + 31546741 = 31546830
109 + 31546721 = 31546830

Showing the first eight; more decompositions exist.
