Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446764, here are decompositions:

3 + 31446761 = 31446764
7 + 31446757 = 31446764
157 + 31446607 = 31446764
211 + 31446553 = 31446764
337 + 31446427 = 31446764
397 + 31446367 = 31446764
523 + 31446241 = 31446764
541 + 31446223 = 31446764

Showing the first eight; more decompositions exist.
