Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596002, here are decompositions:

13 + 31595989 = 31596002
19 + 31595983 = 31596002
73 + 31595929 = 31596002
271 + 31595731 = 31596002
283 + 31595719 = 31596002
331 + 31595671 = 31596002
349 + 31595653 = 31596002
409 + 31595593 = 31596002

Showing the first eight; more decompositions exist.
