Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542972, here are decompositions:

61 + 542911 = 542972
151 + 542821 = 542972
181 + 542791 = 542972
211 + 542761 = 542972
373 + 542599 = 542972
421 + 542551 = 542972
433 + 542539 = 542972
439 + 542533 = 542972

Showing the first eight; more decompositions exist.
