Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473694, here are decompositions:

101 + 31473593 = 31473694
113 + 31473581 = 31473694
257 + 31473437 = 31473694
281 + 31473413 = 31473694
431 + 31473263 = 31473694
443 + 31473251 = 31473694
491 + 31473203 = 31473694
503 + 31473191 = 31473694

Showing the first eight; more decompositions exist.
