Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542902, here are decompositions:

11 + 542891 = 542902
29 + 542873 = 542902
71 + 542831 = 542902
131 + 542771 = 542902
179 + 542723 = 542902
383 + 542519 = 542902
419 + 542483 = 542902
461 + 542441 = 542902

Showing the first eight; more decompositions exist.
