Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542394, here are decompositions:

23 + 542371 = 542394
71 + 542323 = 542394
101 + 542293 = 542394
113 + 542281 = 542394
131 + 542263 = 542394
157 + 542237 = 542394
197 + 542197 = 542394
211 + 542183 = 542394

Showing the first eight; more decompositions exist.
