Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504490, here are decompositions:

37 + 31504453 = 31504490
103 + 31504387 = 31504490
139 + 31504351 = 31504490
163 + 31504327 = 31504490
271 + 31504219 = 31504490
307 + 31504183 = 31504490
439 + 31504051 = 31504490
607 + 31503883 = 31504490

Showing the first eight; more decompositions exist.
