Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472758, here are decompositions:

59 + 31472699 = 31472758
89 + 31472669 = 31472758
167 + 31472591 = 31472758
257 + 31472501 = 31472758
269 + 31472489 = 31472758
419 + 31472339 = 31472758
467 + 31472291 = 31472758
557 + 31472201 = 31472758

Showing the first eight; more decompositions exist.
