Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476442, here are decompositions:

5 + 31476437 = 31476442
29 + 31476413 = 31476442
59 + 31476383 = 31476442
71 + 31476371 = 31476442
89 + 31476353 = 31476442
191 + 31476251 = 31476442
293 + 31476149 = 31476442
383 + 31476059 = 31476442

Showing the first eight; more decompositions exist.
