Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536122, here are decompositions:

61 + 31536061 = 31536122
73 + 31536049 = 31536122
103 + 31536019 = 31536122
139 + 31535983 = 31536122
181 + 31535941 = 31536122
313 + 31535809 = 31536122
571 + 31535551 = 31536122
619 + 31535503 = 31536122

Showing the first eight; more decompositions exist.
