Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489064, here are decompositions:

37 + 31489027 = 31489064
73 + 31488991 = 31489064
157 + 31488907 = 31489064
331 + 31488733 = 31489064
433 + 31488631 = 31489064
571 + 31488493 = 31489064
601 + 31488463 = 31489064
631 + 31488433 = 31489064

Showing the first eight; more decompositions exist.
