Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536044, here are decompositions:

61 + 31535983 = 31536044
97 + 31535947 = 31536044
103 + 31535941 = 31536044
223 + 31535821 = 31536044
373 + 31535671 = 31536044
541 + 31535503 = 31536044
577 + 31535467 = 31536044
733 + 31535311 = 31536044

Showing the first eight; more decompositions exist.
