Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453564, here are decompositions:

41 + 31453523 = 31453564
101 + 31453463 = 31453564
137 + 31453427 = 31453564
173 + 31453391 = 31453564
281 + 31453283 = 31453564
383 + 31453181 = 31453564
431 + 31453133 = 31453564
587 + 31452977 = 31453564

Showing the first eight; more decompositions exist.
