Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536002, here are decompositions:

19 + 31535983 = 31536002
61 + 31535941 = 31536002
181 + 31535821 = 31536002
193 + 31535809 = 31536002
331 + 31535671 = 31536002
409 + 31535593 = 31536002
499 + 31535503 = 31536002
661 + 31535341 = 31536002

Showing the first eight; more decompositions exist.
