Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580034, here are decompositions:

67 + 31579967 = 31580034
181 + 31579853 = 31580034
197 + 31579837 = 31580034
271 + 31579763 = 31580034
293 + 31579741 = 31580034
313 + 31579721 = 31580034
331 + 31579703 = 31580034
373 + 31579661 = 31580034

Showing the first eight; more decompositions exist.
