Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603184, here are decompositions:

37 + 31603147 = 31603184
43 + 31603141 = 31603184
61 + 31603123 = 31603184
73 + 31603111 = 31603184
157 + 31603027 = 31603184
211 + 31602973 = 31603184
307 + 31602877 = 31603184
331 + 31602853 = 31603184

Showing the first eight; more decompositions exist.
