Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476492, here are decompositions:

31 + 31476461 = 31476492
41 + 31476451 = 31476492
43 + 31476449 = 31476492
59 + 31476433 = 31476492
79 + 31476413 = 31476492
101 + 31476391 = 31476492
109 + 31476383 = 31476492
139 + 31476353 = 31476492

Showing the first eight; more decompositions exist.
