Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541246, here are decompositions:

3 + 31541243 = 31541246
13 + 31541233 = 31541246
67 + 31541179 = 31541246
73 + 31541173 = 31541246
199 + 31541047 = 31541246
229 + 31541017 = 31541246
307 + 31540939 = 31541246
379 + 31540867 = 31541246

Showing the first eight; more decompositions exist.
