Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476148, here are decompositions:

5 + 31476143 = 31476148
29 + 31476119 = 31476148
89 + 31476059 = 31476148
131 + 31476017 = 31476148
239 + 31475909 = 31476148
467 + 31475681 = 31476148
479 + 31475669 = 31476148
569 + 31475579 = 31476148

Showing the first eight; more decompositions exist.
