Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519034, here are decompositions:

73 + 31518961 = 31519034
241 + 31518793 = 31519034
277 + 31518757 = 31519034
433 + 31518601 = 31519034
577 + 31518457 = 31519034
607 + 31518427 = 31519034
691 + 31518343 = 31519034
733 + 31518301 = 31519034

Showing the first eight; more decompositions exist.
