Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602042, here are decompositions:

151 + 31601891 = 31602042
179 + 31601863 = 31602042
193 + 31601849 = 31602042
223 + 31601819 = 31602042
233 + 31601809 = 31602042
331 + 31601711 = 31602042
491 + 31601551 = 31602042
503 + 31601539 = 31602042

Showing the first eight; more decompositions exist.
