Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542650, here are decompositions:

47 + 542603 = 542650
71 + 542579 = 542650
83 + 542567 = 542650
113 + 542537 = 542650
131 + 542519 = 542650
167 + 542483 = 542650
389 + 542261 = 542650
431 + 542219 = 542650

Showing the first eight; more decompositions exist.
