Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474002, here are decompositions:

11 + 31473991 = 31474002
31 + 31473971 = 31474002
71 + 31473931 = 31474002
101 + 31473901 = 31474002
139 + 31473863 = 31474002
163 + 31473839 = 31474002
191 + 31473811 = 31474002
193 + 31473809 = 31474002

Showing the first eight; more decompositions exist.
