Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473626, here are decompositions:

43 + 31473583 = 31473626
97 + 31473529 = 31473626
103 + 31473523 = 31473626
139 + 31473487 = 31473626
229 + 31473397 = 31473626
313 + 31473313 = 31473626
409 + 31473217 = 31473626
439 + 31473187 = 31473626

Showing the first eight; more decompositions exist.
