Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453672, here are decompositions:

101 + 31453571 = 31453672
149 + 31453523 = 31453672
251 + 31453421 = 31453672
281 + 31453391 = 31453672
311 + 31453361 = 31453672
389 + 31453283 = 31453672
431 + 31453241 = 31453672
479 + 31453193 = 31453672

Showing the first eight; more decompositions exist.
