Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602002, here are decompositions:

79 + 31601923 = 31602002
139 + 31601863 = 31602002
193 + 31601809 = 31602002
331 + 31601671 = 31602002
373 + 31601629 = 31602002
433 + 31601569 = 31602002
463 + 31601539 = 31602002
643 + 31601359 = 31602002

Showing the first eight; more decompositions exist.
