Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542404, here are decompositions:

3 + 542401 = 542404
167 + 542237 = 542404
197 + 542207 = 542404
251 + 542153 = 542404
263 + 542141 = 542404
281 + 542123 = 542404
293 + 542111 = 542404
311 + 542093 = 542404

Showing the first eight; more decompositions exist.
