Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542804, here are decompositions:

7 + 542797 = 542804
13 + 542791 = 542804
43 + 542761 = 542804
271 + 542533 = 542804
307 + 542497 = 542804
337 + 542467 = 542804
433 + 542371 = 542804
523 + 542281 = 542804

Showing the first eight; more decompositions exist.
