Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563098, here are decompositions:

67 + 31563031 = 31563098
97 + 31563001 = 31563098
139 + 31562959 = 31563098
181 + 31562917 = 31563098
271 + 31562827 = 31563098
331 + 31562767 = 31563098
421 + 31562677 = 31563098
487 + 31562611 = 31563098

Showing the first eight; more decompositions exist.
