Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530742, here are decompositions:

11 + 530731 = 530742
29 + 530713 = 530742
31 + 530711 = 530742
41 + 530701 = 530742
73 + 530669 = 530742
83 + 530659 = 530742
89 + 530653 = 530742
101 + 530641 = 530742

Showing the first eight; more decompositions exist.
