Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495854, here are decompositions:

7 + 31495847 = 31495854
53 + 31495801 = 31495854
97 + 31495757 = 31495854
101 + 31495753 = 31495854
113 + 31495741 = 31495854
163 + 31495691 = 31495854
191 + 31495663 = 31495854
193 + 31495661 = 31495854

Showing the first eight; more decompositions exist.
