Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499102, here are decompositions:

79 + 31499023 = 31499102
109 + 31498993 = 31499102
139 + 31498963 = 31499102
223 + 31498879 = 31499102
463 + 31498639 = 31499102
631 + 31498471 = 31499102
823 + 31498279 = 31499102
829 + 31498273 = 31499102

Showing the first eight; more decompositions exist.
