Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476788, here are decompositions:

61 + 31476727 = 31476788
97 + 31476691 = 31476788
157 + 31476631 = 31476788
181 + 31476607 = 31476788
241 + 31476547 = 31476788
271 + 31476517 = 31476788
331 + 31476457 = 31476788
337 + 31476451 = 31476788

Showing the first eight; more decompositions exist.
