Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476992, here are decompositions:

61 + 31476931 = 31476992
139 + 31476853 = 31476992
163 + 31476829 = 31476992
193 + 31476799 = 31476992
541 + 31476451 = 31476992
601 + 31476391 = 31476992
619 + 31476373 = 31476992
643 + 31476349 = 31476992

Showing the first eight; more decompositions exist.
