Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155754, here are decompositions:

7 + 155747 = 155754
13 + 155741 = 155754
23 + 155731 = 155754
31 + 155723 = 155754
37 + 155717 = 155754
47 + 155707 = 155754
61 + 155693 = 155754
83 + 155671 = 155754

Showing the first eight; more decompositions exist.
