Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580054, here are decompositions:

3 + 31580051 = 31580054
7 + 31580047 = 31580054
223 + 31579831 = 31580054
241 + 31579813 = 31580054
307 + 31579747 = 31580054
313 + 31579741 = 31580054
421 + 31579633 = 31580054
487 + 31579567 = 31580054

Showing the first eight; more decompositions exist.
