Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580264, here are decompositions:

7 + 31580257 = 31580264
31 + 31580233 = 31580264
43 + 31580221 = 31580264
151 + 31580113 = 31580264
181 + 31580083 = 31580264
211 + 31580053 = 31580264
433 + 31579831 = 31580264
523 + 31579741 = 31580264

Showing the first eight; more decompositions exist.
