Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515174, here are decompositions:

31 + 515143 = 515174
241 + 514933 = 515174
271 + 514903 = 515174
307 + 514867 = 515174
433 + 514741 = 515174
463 + 514711 = 515174
523 + 514651 = 515174
613 + 514561 = 515174

Showing the first eight; more decompositions exist.
