Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542002, here are decompositions:

13 + 31541989 = 31542002
31 + 31541971 = 31542002
103 + 31541899 = 31542002
109 + 31541893 = 31542002
241 + 31541761 = 31542002
421 + 31541581 = 31542002
433 + 31541569 = 31542002
439 + 31541563 = 31542002

Showing the first eight; more decompositions exist.
