Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506002, here are decompositions:

13 + 31505989 = 31506002
19 + 31505983 = 31506002
43 + 31505959 = 31506002
79 + 31505923 = 31506002
181 + 31505821 = 31506002
193 + 31505809 = 31506002
271 + 31505731 = 31506002
379 + 31505623 = 31506002

Showing the first eight; more decompositions exist.
