Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498184, here are decompositions:

61 + 31498123 = 31498184
73 + 31498111 = 31498184
97 + 31498087 = 31498184
181 + 31498003 = 31498184
313 + 31497871 = 31498184
433 + 31497751 = 31498184
457 + 31497727 = 31498184
463 + 31497721 = 31498184

Showing the first eight; more decompositions exist.
