Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558048, here are decompositions:

29 + 31558019 = 31558048
89 + 31557959 = 31558048
167 + 31557881 = 31558048
191 + 31557857 = 31558048
239 + 31557809 = 31558048
257 + 31557791 = 31558048
317 + 31557731 = 31558048
479 + 31557569 = 31558048

Showing the first eight; more decompositions exist.
