Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503054, here are decompositions:

61 + 31502993 = 31503054
101 + 31502953 = 31503054
113 + 31502941 = 31503054
127 + 31502927 = 31503054
131 + 31502923 = 31503054
157 + 31502897 = 31503054
173 + 31502881 = 31503054
197 + 31502857 = 31503054

Showing the first eight; more decompositions exist.
