Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467786, here are decompositions:

19 + 31467767 = 31467786
23 + 31467763 = 31467786
59 + 31467727 = 31467786
67 + 31467719 = 31467786
109 + 31467677 = 31467786
139 + 31467647 = 31467786
193 + 31467593 = 31467786
197 + 31467589 = 31467786

Showing the first eight; more decompositions exist.
