Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472804, here are decompositions:

31 + 31472773 = 31472804
193 + 31472611 = 31472804
367 + 31472437 = 31472804
613 + 31472191 = 31472804
661 + 31472143 = 31472804
673 + 31472131 = 31472804
751 + 31472053 = 31472804
1093 + 31471711 = 31472804

Showing the first eight; more decompositions exist.
