Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514608, here are decompositions:

29 + 31514579 = 31514608
71 + 31514537 = 31514608
131 + 31514477 = 31514608
179 + 31514429 = 31514608
311 + 31514297 = 31514608
317 + 31514291 = 31514608
347 + 31514261 = 31514608
449 + 31514159 = 31514608

Showing the first eight; more decompositions exist.
