Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453714, here are decompositions:

3 + 31453711 = 31453714
137 + 31453577 = 31453714
191 + 31453523 = 31453714
251 + 31453463 = 31453714
293 + 31453421 = 31453714
353 + 31453361 = 31453714
431 + 31453283 = 31453714
521 + 31453193 = 31453714

Showing the first eight; more decompositions exist.
