Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474232, here are decompositions:

19 + 31474213 = 31474232
61 + 31474171 = 31474232
103 + 31474129 = 31474232
199 + 31474033 = 31474232
241 + 31473991 = 31474232
331 + 31473901 = 31474232
421 + 31473811 = 31474232
499 + 31473733 = 31474232

Showing the first eight; more decompositions exist.
