Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495932, here are decompositions:

11 + 31495921 = 31495932
53 + 31495879 = 31495932
73 + 31495859 = 31495932
113 + 31495819 = 31495932
131 + 31495801 = 31495932
179 + 31495753 = 31495932
191 + 31495741 = 31495932
199 + 31495733 = 31495932

Showing the first eight; more decompositions exist.
