Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473848, here are decompositions:

37 + 31473811 = 31473848
67 + 31473781 = 31473848
607 + 31473241 = 31473848
631 + 31473217 = 31473848
661 + 31473187 = 31473848
739 + 31473109 = 31473848
787 + 31473061 = 31473848
811 + 31473037 = 31473848

Showing the first eight; more decompositions exist.
