Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042454, here are decompositions:

3 + 1042451 = 1042454
73 + 1042381 = 1042454
97 + 1042357 = 1042454
181 + 1042273 = 1042454
211 + 1042243 = 1042454
271 + 1042183 = 1042454
313 + 1042141 = 1042454
331 + 1042123 = 1042454

Showing the first eight; more decompositions exist.
