Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454574, here are decompositions:

61 + 31454513 = 31454574
113 + 31454461 = 31454574
191 + 31454383 = 31454574
197 + 31454377 = 31454574
223 + 31454351 = 31454574
311 + 31454263 = 31454574
353 + 31454221 = 31454574
373 + 31454201 = 31454574

Showing the first eight; more decompositions exist.
