Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511772, here are decompositions:

61 + 511711 = 511772
103 + 511669 = 511772
139 + 511633 = 511772
181 + 511591 = 511772
193 + 511579 = 511772
199 + 511573 = 511772
223 + 511549 = 511772
421 + 511351 = 511772

Showing the first eight; more decompositions exist.
