Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530088, here are decompositions:

59 + 31530029 = 31530088
71 + 31530017 = 31530088
197 + 31529891 = 31530088
269 + 31529819 = 31530088
419 + 31529669 = 31530088
521 + 31529567 = 31530088
617 + 31529471 = 31530088
641 + 31529447 = 31530088

Showing the first eight; more decompositions exist.
