Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541226, here are decompositions:

47 + 31541179 = 31541226
53 + 31541173 = 31541226
97 + 31541129 = 31541226
109 + 31541117 = 31541226
113 + 31541113 = 31541226
179 + 31541047 = 31541226
359 + 31540867 = 31541226
389 + 31540837 = 31541226

Showing the first eight; more decompositions exist.
