Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484842, here are decompositions:

3 + 31484839 = 31484842
5 + 31484837 = 31484842
41 + 31484801 = 31484842
71 + 31484771 = 31484842
89 + 31484753 = 31484842
101 + 31484741 = 31484842
131 + 31484711 = 31484842
479 + 31484363 = 31484842

Showing the first eight; more decompositions exist.
