Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447598, here are decompositions:

157 + 31447441 = 31447598
241 + 31447357 = 31447598
331 + 31447267 = 31447598
409 + 31447189 = 31447598
499 + 31447099 = 31447598
571 + 31447027 = 31447598
577 + 31447021 = 31447598
601 + 31446997 = 31447598

Showing the first eight; more decompositions exist.
