Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542726, here are decompositions:

3 + 542723 = 542726
7 + 542719 = 542726
13 + 542713 = 542726
43 + 542683 = 542726
127 + 542599 = 542726
139 + 542587 = 542726
193 + 542533 = 542726
229 + 542497 = 542726

Showing the first eight; more decompositions exist.
