Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579094, here are decompositions:

3 + 31579091 = 31579094
7 + 31579087 = 31579094
307 + 31578787 = 31579094
331 + 31578763 = 31579094
373 + 31578721 = 31579094
397 + 31578697 = 31579094
487 + 31578607 = 31579094
571 + 31578523 = 31579094

Showing the first eight; more decompositions exist.
