Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606754, here are decompositions:

13 + 31606741 = 31606754
43 + 31606711 = 31606754
73 + 31606681 = 31606754
97 + 31606657 = 31606754
103 + 31606651 = 31606754
211 + 31606543 = 31606754
331 + 31606423 = 31606754
367 + 31606387 = 31606754

Showing the first eight; more decompositions exist.
