Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498072, here are decompositions:

3 + 31498069 = 31498072
29 + 31498043 = 31498072
131 + 31497941 = 31498072
269 + 31497803 = 31498072
401 + 31497671 = 31498072
503 + 31497569 = 31498072
521 + 31497551 = 31498072
719 + 31497353 = 31498072

Showing the first eight; more decompositions exist.
