Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473458, here are decompositions:

61 + 31473397 = 31473458
127 + 31473331 = 31473458
241 + 31473217 = 31473458
271 + 31473187 = 31473458
307 + 31473151 = 31473458
349 + 31473109 = 31473458
397 + 31473061 = 31473458
421 + 31473037 = 31473458

Showing the first eight; more decompositions exist.
