Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468544, here are decompositions:

73 + 31468471 = 31468544
97 + 31468447 = 31468544
313 + 31468231 = 31468544
397 + 31468147 = 31468544
577 + 31467967 = 31468544
607 + 31467937 = 31468544
691 + 31467853 = 31468544
733 + 31467811 = 31468544

Showing the first eight; more decompositions exist.
