Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473722, here are decompositions:

19 + 31473703 = 31473722
139 + 31473583 = 31473722
193 + 31473529 = 31473722
199 + 31473523 = 31473722
409 + 31473313 = 31473722
439 + 31473283 = 31473722
571 + 31473151 = 31473722
613 + 31473109 = 31473722

Showing the first eight; more decompositions exist.
