Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590044, here are decompositions:

7 + 31590037 = 31590044
37 + 31590007 = 31590044
61 + 31589983 = 31590044
67 + 31589977 = 31590044
271 + 31589773 = 31590044
307 + 31589737 = 31590044
313 + 31589731 = 31590044
337 + 31589707 = 31590044

Showing the first eight; more decompositions exist.
