Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552746, here are decompositions:

13 + 31552733 = 31552746
19 + 31552727 = 31552746
37 + 31552709 = 31552746
53 + 31552693 = 31552746
103 + 31552643 = 31552746
107 + 31552639 = 31552746
157 + 31552589 = 31552746
167 + 31552579 = 31552746

Showing the first eight; more decompositions exist.
