Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474196, here are decompositions:

67 + 31474129 = 31474196
139 + 31474057 = 31474196
163 + 31474033 = 31474196
349 + 31473847 = 31474196
463 + 31473733 = 31474196
613 + 31473583 = 31474196
673 + 31473523 = 31474196
709 + 31473487 = 31474196

Showing the first eight; more decompositions exist.
