Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476390, here are decompositions:

7 + 31476383 = 31476390
17 + 31476373 = 31476390
19 + 31476371 = 31476390
37 + 31476353 = 31476390
41 + 31476349 = 31476390
47 + 31476343 = 31476390
73 + 31476317 = 31476390
107 + 31476283 = 31476390

Showing the first eight; more decompositions exist.
