Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476488, here are decompositions:

31 + 31476457 = 31476488
37 + 31476451 = 31476488
97 + 31476391 = 31476488
139 + 31476349 = 31476488
331 + 31476157 = 31476488
457 + 31476031 = 31476488
577 + 31475911 = 31476488
661 + 31475827 = 31476488

Showing the first eight; more decompositions exist.
