Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542912, here are decompositions:

151 + 542761 = 542912
193 + 542719 = 542912
199 + 542713 = 542912
229 + 542683 = 542912
313 + 542599 = 542912
373 + 542539 = 542912
379 + 542533 = 542912
541 + 542371 = 542912

Showing the first eight; more decompositions exist.
