Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542044, here are decompositions:

7 + 31542037 = 31542044
13 + 31542031 = 31542044
31 + 31542013 = 31542044
43 + 31542001 = 31542044
67 + 31541977 = 31542044
73 + 31541971 = 31542044
151 + 31541893 = 31542044
283 + 31541761 = 31542044

Showing the first eight; more decompositions exist.
