Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018742, here are decompositions:

13 + 1018729 = 1018742
31 + 1018711 = 1018742
73 + 1018669 = 1018742
199 + 1018543 = 1018742
229 + 1018513 = 1018742
271 + 1018471 = 1018742
313 + 1018429 = 1018742
331 + 1018411 = 1018742

Showing the first eight; more decompositions exist.
