Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523490, here are decompositions:

3 + 523487 = 523490
31 + 523459 = 523490
73 + 523417 = 523490
103 + 523387 = 523490
139 + 523351 = 523490
157 + 523333 = 523490
193 + 523297 = 523490
229 + 523261 = 523490

Showing the first eight; more decompositions exist.
