Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146742, here are decompositions:

23 + 146719 = 146742
41 + 146701 = 146742
59 + 146683 = 146742
61 + 146681 = 146742
73 + 146669 = 146742
103 + 146639 = 146742
139 + 146603 = 146742
179 + 146563 = 146742

Showing the first eight; more decompositions exist.
