Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472744, here are decompositions:

157 + 31472587 = 31472744
307 + 31472437 = 31472744
577 + 31472167 = 31472744
601 + 31472143 = 31472744
613 + 31472131 = 31472744
691 + 31472053 = 31472744
733 + 31472011 = 31472744
811 + 31471933 = 31472744

Showing the first eight; more decompositions exist.
