Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542750, here are decompositions:

3 + 542747 = 542750
31 + 542719 = 542750
37 + 542713 = 542750
67 + 542683 = 542750
151 + 542599 = 542750
163 + 542587 = 542750
193 + 542557 = 542750
199 + 542551 = 542750

Showing the first eight; more decompositions exist.
