Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479162, here are decompositions:

31 + 31479131 = 31479162
61 + 31479101 = 31479162
79 + 31479083 = 31479162
89 + 31479073 = 31479162
101 + 31479061 = 31479162
131 + 31479031 = 31479162
179 + 31478983 = 31479162
193 + 31478969 = 31479162

Showing the first eight; more decompositions exist.
