Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474124, here are decompositions:

13 + 31474111 = 31474124
67 + 31474057 = 31474124
193 + 31473931 = 31474124
223 + 31473901 = 31474124
277 + 31473847 = 31474124
313 + 31473811 = 31474124
421 + 31473703 = 31474124
541 + 31473583 = 31474124

Showing the first eight; more decompositions exist.
